Application and implications of polyethylene glycol-fusion as a novel technology to repair injured spinal cords

Conventional vs. polyethylene glycol （PEG）-fusion tech- nologies to repair severed spinal axons： Most spinal cord injuries （SCIs） involve cutor crush-severance of spinal tract axons in the central nervous system （CNS）. Clinical out- comes after CNS axonal severance is very poor because proximal segments of CNS axons lack a suitable environment for outgrowth （Kakulas, 1999; Fitch and Silver, 2008; Rowland et al., 2008; Kwon et al., 2010） and therefore do not naturally regenerate （Ramon y Caial, 1928）. Current strategies to try to increase behavioral recovery after SCI are focused on en- hancing the environment for axonal outgrowth.

Application Technology of Tebuconazole WG against Sheath Blight 75% Trifloxystrobin · Rice Blast and Rice

[ Objective] The paper was to confirm the best application period and frequency of 75% trifloxystrobin ·tebuconazole WG against rice blast and rice sheath blight. [ Method] Influences of different dosages and different application periods of 75% trifloxystrobin · tebuconazole WG on control effects against rice blast and rice sheath blight, as well as their effects on rice yields were studied in the paper. [Result] The control effects of three different fungicides application treatments against rice sheath blight were 80.24%, 83.0% and 67.99%, and the control effects against rice blast were 56.4%, 49.11% and 61.1%, respective- ly. Advanced application of fungicide for two times had good prevention effect against rice sheath blight ; properly delayed application of fungicides for two times was conducive to improving the control effect against rice blast, and one time application of sufficient fungicide during middle booting stage had higher control effect than application for two times. Effective panicle number per unit area, total grain number, 1 000-grain weight and moisture content of various fungicide application treat- ments did not have significant difference with those of the treatments without fungicide application, but grain number per panicle in treatments applied with fungicide was higher than the treatment without application. [ Conclusion] 75% Trifloxystrobin ·tebuconazole WG has better control effect on rice blast and sheath blight, which helps to promote the formation of rice grain and increases yield significantly. The fungicide application against rice sheath blight should be appropriately ad- vanced, and application for one time against panicle blast after middle booting stage is helpful to improve the control effect.

Guest Editorial First Issue on the Special Section on Terahertz Technology and Applications

During the past few years, the terahertz （THz） frequency regime has had renewed scientific and technological interest because of recent breakthroughs in the areas of high power sources, sensitive detectors, novel materials, and high resolution video imaging. Because it lies between the radio frequencies and infrared wavelengths, the terahertz electromagnetic region was thought to be promising for practical applications （300 micrometers wavelength corresponds to 1 THz frequency）, but it suffered from very high attenuation through the atmosphere （above 1 dB/meter）, and was found to be difficult to generate, modulate, and detect. On the other hand, many non-polar dielectric materials are transparent to THz waves,

Application of Multimedia and Internet Technology in Learning Mould Design

With the use of multimedia which combines the use o f text, sound, images, motion video and animation, it is more efficient for studen ts to learn mould design interactively. A program is created using several multi media software to simulate the mechanism of moulding processes in order to let s tudents understand the concept of mould design. In addition, students can even access the program through the Internet. Therefore, the software is defined as Multimedia and Internet Technology (MIT) program. The MIT program consists of four sections: (i) simulation of mould mechanisms, ( ii) cooling system, (iii) material information and (iv) games for tutorials. Sec tion One covers the basic operations of different types of moulds such as two-p late mould, three-plate mould, split mould, side-core mould and mould with und ercuts. Section Two introduces different types of cooling systems such as bubble r, baffle, cooling circuits, etc. Section Three provides some useful material in formation for mould design. Section Four contains games of matching mould compon ents, mould design problem finding and multiple choice questions to test student s how much they understand mould design concept. Multimedia is highly effective particularly in teaching and learning. It changes the nature of learning itself. It makes reading dynamic by giving words an impo rtant new dimension. It allows students to see, hear and do simultaneously, thus significantly reducing average learning time. Furthermore, through cooperative learning on Internet, students can access the program, share data or search info rmation anytime anywhere. Therefore, Multimedia and Internet Technology is one o f the vital aspects to speed up the realization of information age in society.
