Published: February 2012

Chatter is the most obscuring phenomenon and significant amount of research has been documented regarding prediction, control and elimination of chatter. The present study has been undertaken in order to investigate the effects of multilevel dynamics in the dynamic stability prediction of deep end milling of the flexible parts. In the course of development of stability lobes diagram (SLD), input parameter of structure dynamics plays a vital role on the precision of SLD. In the present study CutPro is used to develop SLD for deep end milling of flexible workpiece after considering two cases of frequency response function (FRF) identification of flexible workpiece. It is shown that for deep end milling of flexible workpiece it is not enough to just identify the FRF of the workpiece only at one free end of the workpiece. To develop the exact and precise SLD it is necessary to identify the FRF of the flexible workpiece at more than one point along the axial depth depending upon how deep the workpiece is being milled.

Charge Transport and Ultrasonic Properties of La1/3Sr2/3Fe0.95Co0.05O3Perovskite
Authors: Kong Hui , Dai Wei , Shao Shuai
Published: February 2012

The longitudinal ultrasonic velocity (V) and attenuation at a frequency of 10MHz have been measured in single-phase polycrystalline La1/3Sr2/3Fe0.95Co0.05O3 from 20K to 300K. The temperature dependence of resistivity indicates that La1/3Sr2/3Fe0.95Co0.05O3 undergoes charge ordering transition at TCO. A dramatic increase in V is observed at TCO, which is accompanied by a sharp peak in attenuation. This simultaneous occurrence of resistivity and ultrasonic anomalous features implies extremely strong electron-phonon interaction, which is due to the the Jahn-Teller effect of high-spin Fe4+. Below TCO, another softening in V accompanied by a wide ultrasonic attenuation peak is observed. The analysis of the results suggests that these anomalies may correspond to the breathing-type distortion of Fe-O octahedron.

The result showed that P. amabilis population is most clumped. The result indicated the pattern intensity was decreasing with the size increasing and a single peak value appeared in the curve with the area increasing. There was a slow change in the pattern intensity of population, which means a smaller variation in environment and a bigger difference in the relative density of population patches during diffusion process.

Published: February 2012

The relationship between the ratio of styrene-acrylic latex to ordinary Portland cement (OPC) and the nitric acid corrosion resistance of latex modified ordinary Portland cement mortar was studied. The compressive strength and flexural strength of latex modified cement mortar in the nitric acid solution at different ages were tesed and the samples appearance was observed. The results show that the nitric acid corrosion resistance of latex modified OPC mortar is influenced positively by the latex/cement ratio. With the ratio of emulsion to cement increasing, the nitric acid corrosion resistance ability of OPC mortar was enhanced firstly and then decreased. When the polymer/cement ratio was 0.2, the latex modified cement mortar showed the best performance in compressive strength, flexural strength, and the appearance.

Perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) have emerged as two concerning contaminants in recent years. However, there is limited information about their mixture toxicity to aquatic organisms. In the present study, the single and mixture toxicity of PFOA and PFOS to zebrafish (Danio rerio) embryo were tested, and the mixture toxicity was predicted by concentration addition (CA) and independent action (IA) models. It is found that PFOS and PFOA have synergistic effect at 96 hpf, while this kind of synergistic effect is not obvious at 72 hpf. CA and IA models both could predict the 72 h mixture toxicity, while underestimate the 96 h mixture toxicity.

Published: February 2012

Using calcined sulfate-modified titanium-bearing blast furnace slag (STBBFS) as photocatalyst, decolorization efficiency of methyl orange (MO) in the presence of Cr(VI) were studied. The effect of solution pH on the decolorization efficiency of MO and reduction efficiency of Cr(VI) have been investigated. The results indicate that the acidic solutions are favorable for the photocatalytic oxidation of MO in the presence of Cr(VI), and the optimum pH for oxidation of MO is 1.5. The increasing of photocatalytic activities in the compound system can be attributed to five main reasons: (1) the redox reaction between Cr(VI) and MO; (2) adsorption of Cr(VI) species and dye molecule onto STBBFS surface; (3) the visible light irradiation; (4) Cr(VI) species reduced to Cr(III) by Mn2+ in STBBFS photocatalyst; (5) Moreover, the addition of Cr(VI) species able to act as electron scavengers to catalyst surface promotes the effective separation of electron-hole, and hence promote the increase of decolorization efficiency of MO and reduction efficiency of Cr(VI) in Cr(VI)-MO system under visible irradiation. UV-vis spectral analysis indicated that MO was completely mineralized in the presence of Cr(VI) after 240 min. FTIR spectral analysis showed that all these characteristic peaks of Cr(VI) and MO disappear after photoreaction, indicating the degradation of Cr(VI) and MO.

Published: February 2012

Traditional tendon repair methods mainly used autogenous tendon transplantation and autogenous tendon transfer, but the development of two repair methods may be greatly limited due to the limited donor site and the added trauma. At the present time, the research on tissue-engineered tendon has made significant progress. The sources of seed cells for tendon repair cannot be limited to the autogenous tendon cells; we should make gene transformation to mechanocyte through gene chips method in order to resolve the problems related with sources of seed cells of tissue engineered tendon. The well-balanced mechanical stimulation is very important in tendon regeneration process. This stimulation on realignment of neonatal tendon collagen fibers and improve mechanical strength is necessary, which can guarantee implementation of early functional exercise, reducing tendon adhesion, and make tendon repair process into a virtuous circle.
