The effect of characteristics flow (contour of velocity), mass transfer (Sherwood number) and heat transfer (Nu number) on the growth rate of silicon carbide by means of plasma-enhanced chemical vapor deposition vertical reactor is investigated. The species transport and thermal fluid transport with chemical reaction are taken into account. The steady-state laminar fluid flow and gas flow having ideal behavior are considered. A mixture of silane and propane (2% molar) as main reactant gases and hydrogen (96% molar) as propellant gas are injected into the reactor. Four different diameters of shower head, three different substrate rotation speeds and five different temperatures of the substrate are used. The finite volume method is employed to solve the problem. The governing equations are solved by upwind differencing scheme. The assumption of speed–pressure coupling leads to use of semi-implicit method for pressure-linked equations to solve the governing equation. It is found that the deposition rate reduces with the shower head diameter and value of substrate temperature and enhances with rotational speed of the substrate. Furthermore, the best shower head diameter to achieve maximum rate of deposition is 1 mm. At the end, a comparison as a limiting case of the considered problem with the existing studies is made. Comparing the results of this experiment with prior studies has shown acceptable consistency.

With the emerging of next generation Intemet protocol (IPv6), it is expected to replace the current version of Internet protocol (IPv4) that will be exhausted in the near future. Besides providing adequate address space, some other new features are included into the new 128 bits of IP such as IP auto configuration, quality of service, simple routing capability, security, mobility and multicasting. The current protocol analyzer will not be able to handle IPv6 packets. This paper will focus on developing protocol analyzer that decodes IPv6 packet. IPv6 protocol analyzer is an application module,which is able to decode the IPv6 packet and provide detail breakdown of the construction of the packet. It has to understand the detail construction of the IPv6, and provide a high level abstraction of bits and bytes of the IPv6 packet.Thus it increases network administrators' understanding of a network protocol,helps he/she in solving protocol related problem in a IPv6 network environment. 相似文献

This study aims to investigate the effect electron beam (EB) irradiation on the polypropylene/devulcanized sulfur cured rubber (PP‐DVC) compound. The PP‐DVC compounds were compounded using twin‐screw extruder and then compression molded into required shapes before irradiation begins. The gel content of all irradiated PP‐DVC compounds gradually increased with higher irradiation dose indicated that the presence of DVC plays an important role in crosslinking enhancement. The mechanical properties of PP‐DVC compounds were observed marginally higher at low irradiation dosages (≤50 kGy). However, higher irradiation dosages up to 200 kGy cause adverse effect to the PP‐DVC compounds. In addition, the application of low irradiation dosage could enhance the dispersion of DVC particles at 20 phr composition in PP matrix. This also found that the scanning electron microscopy (SEM) observation where the DVC particles dispersed better in PP matrix compared to that of nonirradiated samples. Further increment in irradiation dosages up to 200 kGy reduced the crystallinity caused by chain scissoring process could rupture the crystalline structure in PP matrix. It was also found that the wavenumber of the C? H and CH2 groups for irradiated samples reduced at high irradiation dosages due to the formation of carbonyl group. POLYM. ENG.

Quasi‐static and dynamic performances of an epoxy adhesive with and without Boron nitride nanotubes (BNNTs) are studied here. This article investigates the thin film shear and bulk tensile properties of EPON 828/Epikure 3223. In addition to the neat epoxy material, specimens with 1 and 2 wt% concentrations of BNNTs were also tested. Double‐lap shear tests were performed at strain rates ranging from 4.0 × 10−4 to 3.7 × 103 s−1 and it was found that neither the incorporation of BNNTs nor increasing the strain rate had a substantial effect on the shear properties of the thin adhesive layer. However, bulk tensile properties were seen to be sensitive to changes in strain rate. An increase in the strain rate from 5.5 × 10−4 to 1.2 × 102 s−1 increased the tensile strength and Young's modulus by 39 and 113%, respectively; while the failure strain decreased by 49%. Additionally, the BNNT‐modified tensile specimens demonstrated up to 7% increase in tensile strength, up to a 16% increase in modulus, and a 9% decrease in the strain at failure. These results along with electron micrographs showed that due to pull‐out and bridging mechanisms of the nano‐reinforcements, the BNNTs are more effective in normal stress dominant applications, as opposed to shear stress.

Glycogen synthase kinase-3 (GSK-3), a serine/threonine kinase, is a vital glycogen synthase regulator controlling glycogen synthesis, glucose metabolism, and insulin signaling. GSK-3 is widely expressed in different types of cells, and its abundant roles in cellular bioregulation have been speculated. Abnormal GSK-3 activation and inactivation may affect its original bioactivity. Moreover, active and inactive GSK-3 can regulate several cytosolic factors and modulate their diverse cellular functional roles. Studies in experimental liver disease models have illustrated the possible pathological role of GSK-3 in facilitating acute hepatic injury. Pharmacologically targeting GSK-3 is therefore suggested as a therapeutic strategy for liver protection. Furthermore, while the signaling transduction of GSK-3 facilitates proinflammatory interferon (IFN)-γ in vitro and in vivo, the blockade of GSK-3 can be protective, as shown by an IFN-γ-induced immune hepatitis model. In this study, we explored the possible regulation of GSK-3 and the potential relevance of GSK-3 blockade in IFN-γ-mediated immune hepatitis. 相似文献

This work was conducted to investigate the interactive effect of carbon nanotubes (CNTs) and montmorillonite (MMT) on the mechanical–physical properties of the polyvinyl alcohol (PVOH) nanocomposites. The increasing of CNTs amounts from 0.5 phr to 1 phr has gradually increased tensile strength and Young's modulus of all PVOH/MMT blends due to good interaction effect between MMT and CNTs with PVOH matrix especially for 2 phr MMT added PVOH blends. Besides, the addition of low CNTs amounts (≤1 phr) in PVOH matrix has significantly weakened the hydrogen bonding polymer matrix of all PVOH/MMT blends as evaluated in FTIR analysis. This is attributed to the good of dispersion of low amounts of CNTs could disturb the hydrogen bonding between PVOH molecules and thus induced the strength of O? H stretching in PVOH matrix. However, higher amounts of CNTs (≥1.5 phr) have significantly increased hydrogen bonding in PVOH matrix due to the agglomeration of higher amounts of CNTs particles in PVOH matrix as observed in Fourier transform infrared spectroscopy and scanning electron microscopy analysis. From X‐ray diffraction and transmission electron microscopy observation, the MMT particles were found to effectively exfoliate in PVOH matrix of 2 phr MMT (low amounts) added PVOH/MMT/MCNTs composites, indicates that low MMT amounts could improve the interaction effect between PVOH matrix and CNTs particles. In conclusion, the incorporation of lower amounts of CNTs has effectively improved on the mechanical and physical properties of all PVOH and PVOH/MMT blends. J. VINYL ADDIT.
