Rock Fracture Mechanics Simulation in LS-DYNA Discrete Element Method - Bok av Ardalan Amiri - Häftad

Rock Fracture Mechanics Simulation in LS-DYNA Discrete Element Method - Bok av Ardalan Amiri - Häftad

This book is a practical investigation of Discrete Element Method and Bounded Particle Method in LS-DYNA using real world sandstone tests data as calibrators and references. The methods, with a critical approach and merit based comparison, were mainly evaluated within the frame of the code formulas. However, some subroutines using the code standard language and MATLAB scripting were also applied to hopefully extend the capabilities. The content of this book shall be exploited further in other publications..

Efficacy of Neem Tree Extract on Cabbage Aphids' Control in the Field - Bok av Evaline Stella Amongi, Marius Flarian Murongo, m.fl. - Häftad

Efficacy of Neem Tree Extract on Cabbage Aphids' Control in the Field - Bok av Evaline Stella Amongi, Marius Flarian Murongo, m.fl. - Häftad

Neem tree extracts from root, bark and leaves have generally been used in the control of pests. The extracts¿ efficacy in the control of aphids in cabbages under smallholder farming systems formed the subject of the study. The dose of the admixture of the extract that effectively controlled aphids was determined through experimental methods that involved harvesting and crashing 0.1×10-4 of Neem tree parts. The extract was fermented for 18-48hours.Treatment tests solutions varied were 20mL, 30mL..
