Nowadays it is commonly considered that high damping materials which have both the good mechanical properties as structural materials and the high damping capacity for vibration damping are the most direct vibration damping solution. In metals and alloys however, exhibiting simultaneously high damping capacity and good mechanical properties has been noted to be normally incompatible because the...

considering the deleterious effects of chemical pesticides used in agriculture including cotton cultivation, the search about integrated control strategies for important cotton diseases, verticillium wilt and rhizoctonia seedling damping-off is clearly obvious. in this present study, the researcher investigated the effectiveness of the integration of two strategies, biological control (using an...

the resonant frequency and sensitivity of an atomic force microscope (afm) cantilever with assembled cantilever probe (acp) have been analyzed and a closed-form expression for the sensitivity of vibration modes has been obtained. the proposed acp comprises an inclined cantilever and extension, and a tip located at the free end of the extension, which makes the afm capable of topography at sidew...
