Mechanoreceptors of the insect play a vital role in insect to sense and monitor the environmental parameters like flow, tactile pressure, etc. This paper presents the studies made on the morphology of the mechanoreceptor of insect Blattella Asahinai (scientific name of cockroach), which is a hair-like structure known as trichoid sensilla, by Scanning Electron Microscope and Confocal Laser Microscope. The scanned images show the details of sensilla components in which the hair is embedded in the socket which are connected with the cuticle and joint membrane where the dendrite touches at the base of the hair passing through the cuticle layers. The images also show that the tubular bodies and microtubules are tightly compacted inside the dendrite. This paper presents the details of how the sensilla works when an external stimulus act on it. The hair deflects with the disturbance of the cuticle and joint membrane and this deformed hair lean on the dendrite which is attached at the base of the hair which in turn presses the tubular bodies and microtubules which develop negative ions passing down through the dendrite to the neuron which provides information as an electric signal to the brain of the insect so that it responds for necessary action. Based on the morphological studies, sensing mechanism, material properties of the components, design principles will be evolved for the development of an artificial bio-inspired sensor. A solid works model of the sensilla is also presented.
<b> </b>Ultra high pressure technology is a new type of non thermal processing technology; it is mainly through the structure of the cell wall and cell membrane and cell space destruction of microorganisms, the protein composition of degeneration, the enzyme activity decreased to achieve the purpose of sterilization. This article from the ultra high pressure technology in aquatic products industry, meat industry and fruit and vegetable and its products industry and other aspects of the application status and development direction of ultra high pressure sterilization technology, hope to be able to provide certain support theory in the study of ultra high pressure technology.
Through the process analysis of vehicle damper which involved methods of IE(Industrial Engineering), we can find work load imbalanced procedures. In that way, it changed process procedure, shorten the distance in logistics transportation, changed the chaotic production field. At the same time, we used process analysis and production analysis on the key operation, reallocated word and improved arrangement of work field [, laid off unnecessary works, shortened the working time and production cycle. As a result, the working intensity is reduced.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
