sonics empire Mice infected with 60 cercariae of Schistosoma mansoni were more resistant to the sarcoma 180 ascites tumor.Tumor inoculation was performed 50 days after schistosoma infection and the animals were observed and weighed at 48 hours intervals for development and progression of malignancy.In infected mice the weight gain (ascites formatio
Multi-speed transmission can greatly improve the power and economic performance of electric vehicles (EVs) compared with single-speed transmission.Gear ratio is the key design parameter of multi-speed transmission.Optimizing gear ratios can further improve vehicle performance.Most of the existing optimization methods of gear ratios take the power a
At present, urban expansion represents one of the major challenges that cities must resolve.The phenomenon of urban growth involves a spatial transformation that has been accompanied by negative effects such as extensive use of land, the excessive use of motorized means of transport, environmental impacts, increased costs or social segregation.Soci
A supervisory control system using Model Predictive Control (MPC) has been designed to evaluate the efficiency of wind and eco balloons solar power and is consistent with the cost function in the supervisory MPC optimization problem.A two-layer Economic Model Predictive Control (EMPC) framework has been developed and has improved results such as co
Abstract Shifting cultivation, an age-old agricultural practice, is a major factor in forest cover change across Southeast Asia, where repeated cycles of vegetation disturbance and regrowth lead to far-reaching environmental and socio-economic impacts.The present study aims to assess the spatio-temporal patterns of vegetation disturbance and regrow
