CHARACTERISTICS OF RESONANCE SOUND IN A CIRCULAR SAW ENCLOSURE

Characteristics of Resonance Sound in a Circular Saw Enclosure

Several studies have been conducted to reduce the idling noise of circular saws because the sound level is extremely high and harms the environment.However, conventional noise suppression technology only controls the vibrations of the circular saw itself, whereas idling noise can be generated when the air inside the enclosure is resonant.In this st

Isolation of antibacterial response genes from the dung beetle Copris tripartitus (Coleoptera: Scarabaeidae) immunized with Escherichia coli

Dot blot hybridization of total RNA from normal and bacteria-injected larvae of the dung beetle Copris tripartitus identified 13 cDNA clones that seem to be associated with the immune response.A cDNA encoding read more a dung beetle homolog of the heat shock protein HSP70 (CTHSP70) was characterized by full-length sequencing and expression pattern
