Grafting of CNT on the ramie fabric The schematic representation for the mechanism of ramie fiber surface treatments is shown in Fig. 2. For the alkali treatment of ramie fiber, the NaOH reacts with the hydroxyl groups of the ramie fiber as shown in Fig. 2(a). During silane treatment, the hydrolysis of silane takes place initially (Fig. 2(b)) which then reacts with the active hydroxyl functionalities in ramie fiber (Fig. 2(c)). Each silane molecule has three silanol (Si-OH) groups. For CNT…

rays(laser beams) into electronic signals, into a form ie readable. Fiber optic sensors have numerous advantages over other conventional electronic sensors. Some important advantages are as below • Ability to integrate different structure. • Their inability to conduct electric current. • Highly resistive to electromagnetic interference. • Lightweight with high sensitivity. • Multiplexing capability. 1.1 Optical fiber: Basics An optical fiber is composed of three parts…

Carbon fibers are exceptionally stronger than carbon bulk material. These fibers have very small diameters, typically ranging from 4 to 10 micrometers, which in turn yield a relatively small fiber surface area. Flaws such as dislocations, cracks, and impurities, are virtually inexistent in a specimen of such size, and so the structure is virtually defect free. Because the fibers are kept separated from one another by the matrix, they do not make contact, and crack propagation from fiber to fiber…

that parallel fiber-to-Purkinje cell synapses were strengthened during learning; in contrast, Albus postulated that the parallel fiber-to-Purkinje cell synapses would weaken (he also thought they could strengthen and that the parallel fiber-to-stellate cell synapses were also modifiable.) Albus defended his synaptic weakening argument by pointing out that the parallel fibers should be trained to emulate the post-complex spike pause and not the excitatory phase of the climbing fiber-induced…

cable, Wi-Fi and fiber optic as our media. Ethernet Technology The Ethernet technology was mostly used in the LAN because; 1. We used Ethernet speed of 10mbps for areas in the LAN that required higher bandwidth 2. Our campus network model supports dual links between each distribution layer routers and case switches. We are there able to load balance the aggregate traffic from multiple access switches across the links. 3. Giganet Ethernet will be used between switches but Fiber will be used…

3. Dietary fiber helps the body pass out solid waste (feces). It is found mostly in fruits, vegetables, and brown (whole) grains. Did you get enough dietary fiber in your diet? Explain where you got your dietary fiber from. During that particular week, I feel that I got enough dietary fiber in my diet as I met the recommended servings of grains and was only 2 servings away from meeting the recommended servings of fruits and grains. I got my dietary fibre from dosa (a tamil dish which is a…

Implementation of optical fiber sensor in biomedical Optical fiber sensor for biomedical application Applications for biomedical sensors can be named in vivo or in vitro. In vivo alludes to application on an entire, living life form, for example, a human patient; in vitro alludes to testing outside the body, for example, research facility blood tests. From the point of view of how sensors are connected to a patient or organic framework, they can be named noninvasive, reaching (skin surface),…

of the operation of optical fibers. Just by altering and controlling the angle at which light is incident on the fiber, we can transmit this light signal efficiently. By this principle of Total Internal Reflection the ray of light is trapped within the denser glass of the center of the composite cylindrical glass fiber, the core as if it is guided down the core in a zigzag path of successive reflections. These light waves are guided through the core of the optical fiber just like a radio…

muscle fibers in the presence of ATP contracted 0.07cm and 3.3% change. Under the microscope, figure 1 shows the striated fiber by clearly indicating the bands and lines of the striation. In addition, solution B, with ATP plus Salt (KCl, MgCl2) contracted the muscle fiber by 0.24cm and 9.2% change. Finally, solution C, containing only salt (KCl, MgCl2) also contracted the muscle fiber by 0.13cm and 6.1% change. Figure 2 shows the effect after adding salt and shows the striations of the fiber.…

A final study that was explored focused on the importance of finite element analysis for analyzing the effects of composite patching on CCT. According to [S3], FE analysis is helpful because it leads to a direct computation of both the SIF and stress-distribution field. This study used 2024-T3 aluminum with a glass and epoxy composite patch. Cyclic stress was applied to patched and unpatched aluminum specimens, and the Mindlin FE Approach was used to analyze the resulting data. Results showed…
