The SEM images show the shape and scattering of the trichoid mechanosensilla over the N. rugosus flagellomere. The TEM images present the ultrastructural components, in which the hair rises from the socket via the joint membrane. The dendrite sheath is connected at the base of the hair shaft, surrounded by the lymph space and the socket septum. This dendrite sheath contains a tubular body with microtubules separated by the membrane (M) and granules (Gs). This study presents a model and simulation of the trichoid sensilla sensing mechanism, in which the hair deflects due to the application of external loading above it and presses the dendrite sheath attached to the hair base. The dendrite sheath is displaced by the applied force, transforming the transversal loading into a longitudinal def...

By gradually varying the volume fraction of constitute materials, it not only combines the desired merits of several materials, such as the thermal resistance ability of ceramics and the strength of metals, but also eliminates the interlaminar stresses that usually exist in the traditional laminated composites. In this thesis, the analytical investigation is done by using functionally graded materials for beams and plates for their strength, vibrations and buckling behaviour. The Functionally Graded Material with metal Aluminum alloy 6061 using Ceramic as interface zone is taken for analysis. FGM's are considered for volume fractions of K=2 and K=4.Theoretical calculations are done to compute the material properties for each layer up to 10 layers.

Biocompatible water soluble cellulose composites are used in medical applications as well. Nano cellulose fibers are extracted through various chemical and mechanical treatments to separate the cellulose and to further refine it. Composites are made using thermosetting polyester resin and biodegradable poly vinyl (PVA). A research work is proposed in this paper for extraction of lignocellulose and nano cellulose fibers from century plant and developing the composites for evaluation of TGA, DSC, DMA, dielectric, tensile, flexural, impact, hardness and hygroscopic properties. Applications for the composites will be suggested based on the the properties of the composites.

Medical image databases are currently available to supply clinical diagnosis. For instance, it is possible to provide diagnostic information based on an imaging biomarker comparing a single case to the reference group (controls or patients with disease). At the same time many sophisticated and computationally intensive algorithms have been implemented to extract useful information from medical images. Many applications would take great advantage by using scientific workflow technology due to its design, rapid implementation and reuse. However this technology requires a distributed computing infrastructure (such as Grid or Cloud) to be executed efficiently. One of the most used workflow manager for medical image processing is the LONI pipeline (LP), a graphical workbench developed by the Laboratory of Neuro Imaging (http://pipeline.loni.usc.edu). In this article we present a general approach to submit and monitor workflows on distributed infrastructures using LONI Pipeline, including European Grid Infrastructure (EGI) and Torquebased batch farm. In this paper we implemented a complete segmentation pipeline in brain magnetic resonance imaging (MRI). It requires time-consuming and data-intensive processing and for which reducing the computing time is crucial to meet clinical practice constraints. The developed approach is based on web services and can be used for any medical imaging application.

The scanned images show the details of sensilla components in which the hair is embedded in the sockets, 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 work when an external stimulus act on them. The hair deflects with the disturbance of the cuticle and joint membrane, and this deformed hair leans on the dendrite, which is attach...
