In this study, we measured the body weight, body length, jump height, jump length, and climbing abilities of three species of frogs indigenous to Taiwan. The results were used to design an amphibian corridor suitable for amphibian mobility. Twenty specimens for each of the three species, Rana adenopleura, Rana latouchii, and Kurixalus idiootocus, were collected for testing. Their climbing ability on different matrix angles, materials, temperatures, and humidity were tested. The results showed that the jump height and jump length of the three frog species were in a descending order of R. adenopleura>. R. latouchii>. K. idiootocus. When tested in different climatic environments and climbing matrices, female frogs of all three species showed better climbing ability than that of male frogs. Generally speaking, the influence of climatic conditions on climbing ability was in a descending order of high temperature and high humidity. >. high temperature and low humidity. >. low temperature and high humidity. >. low temperature and low humidity. The steeper the matrix slope, the lower the climbing ability. The findings can provide useful reference for researchers of amphibian corridors in the future. © 2015 Elsevier B.V..

In this study, we found a novel property of graphene and KBrO3 as double and enhanced collaborative catalysts to degrade amoxicillin (AMX) on the photocatalytic behavior of TiO2 nanotubes under UVA light irradiation. The synthesis of graphene-TiO2 nanotubes (GN-TNT) is a necessary first step. AMX can be photo-degraded with GN-TNT, but its degradation rate reaches nearly 100% with the addition of KBrO3, which has two roles in photo-degradation. Its first and more important function is the prevention of electron-hole recombination by acting as electron acceptor. Its second function is its direct participation as oxidant in the degradation of AMX. The effects of GN loading, KBrO3 initial concentration, and AMX concentration on photocatalytic activity are explored in this study. Results of the kinetic study also show that degradation can be expressed by a first-order reaction kinetic model. The degradation mechanism of photocatalytic activity and the role of KBrO3 are also discussed. © 2016 Elsevier Ltd. All rights reserved.

Establishment and characterization of two cobia, Rachycentron canadum, cell lines derived from cobia brain (CB) and cobia fin (CF) are described. Caudal fin and brain from juvenile cobia were dissociated for 30 and 10 min, respectively, in phosphate-buffered saline containing 0.25% trypsin at 25 °C. The optimal culture condition for both dissociated cells (primary cell culture) was at 28 °C in Leibovitz-15 medium containing 10% foetal bovine serum. The cells have been sub-cultured at a ratio of 1:2 for more than 160 passages over a period of 3 years. Origin of the cultured cells was verified by comparison of their sequences of mitochondrial cytochrome oxidase subunit I genes (cox I) with the cox 1 sequence from cobia muscle tissue. The cell lines showed polyploidy. No mycoplasma contamination was detected. Susceptibility to grouper iridovirus was observed for the CB cell line but not the CF cell line. Both cell lines expressed green fluorescent protein after being transfected with green fluorescent reporter gene driven by the cytomegalovirus promoter. © 2009 Blackwell Publishing Ltd.

In recent years, the micro-electro-mechanical systems (MEMS)-based inertial sensors fabrication technology became matured. The technology created inertial sensors greatly enhance the stability, miniature the size, and reduce the cost Therefore, smartphones or mobile phones are embed many kinds of sensors. These sensors can provide many useful data, enabling new applications in various domain such as pedestrian navigation system, fall detection, and activity recognition. In this paper, we focus on the MEMS-based magnetometer, which can detect earth's magnetic field and guide directions. However, magnetometer is susceptible to interference resulted from ferrous material. This study presents the implementation of magnetometer's measurements on Android-based platform, observes the interference phenomenon by realistic measurements, and uses the compensation algorithms to calibrate. © 2014 IEEE.

Graphene oxide (GO) films with two-dimensional structure were successfully prepared via the modified Hummer method. It is proven that redox method is a promising way to synthesize GO films on a large scale. Comprehensive characterizations of the properties of GO films were conducted. TEM and DFM analyses showed that GO sheets prepared in this study had single and double lamellar layer structure and a thickness of 23 nm. X-ray diffraction (XRD) was selected to measure the crystal structure of GO sheet. Fourier-transform infrared spectra analyzer (FT-IR) was used to certify the presence of oxygen-containing functional groups in GO films. The tests of UV-VIS spectrometer and TGA analyzer indicated that GO sheet possessed excellent optical response and outstanding thermal stability. Elemental analyzer (EA) and X-ray photoelectron spectroscope (XPS) analyzed the components synthetic material. Simultaneously, chemical structure of GO sheet was described in this study. Discussion and references for further research on graphene are provided. © 2014 Jianguo Song et al.
