1. INTRODUCTION Despite the generally strict production control of precast concrete members, cracks can occur from time to time in the production process. Most of such cracks are found immediately after steam curing. It is therefore important to grasp the mechanical properties of concrete under steam curing, to elucidate the mechanism of cracking of this sort. Though strength development of concrete during steam

Optimal stocking densities were investigated for the sea cucumber Apostichopusjaponicus Selenka under feed-supplement and non-feed-supplement regimes in net enclosures for 333 d. Substantial weight loss occurred during the aestivation phase （AE）. Decreased growth rates were also observed during the winter phase （WT）. In contrast, sea cucumbers showed rapid growth during the spring （SP） and autumn （AU） phases. Feeding regimes considerably influenced the growtb performance, i.e., sea cucumbers grew faster under feed-supplement regime than under non-feed-supplement regime （P 〈 0.05）. The average survival rates of sea cucumbers under feed-supplement regime were higher than those under non-feed-supplement regime for both the autumn phase and spring phase, but the differences were only significant for the latter phase （P〈 0.05）. The fitted B-N curves showed that the optimal stocking densities, in terms of net production, were 22.3 ind. m^-2 for feed-supplement regime and 14.1 ind. m^-2 for non-feed-supplement regime.

Development of a low-carbon economy and reduction of carbon emissions is the trend of future global socio-economic change, and the only way to mitigate climate change under the frame- work of sustainable development. Based on the concept of a low-carbon economy, the author at- tempts to find a way for underdeveloped regions, which can satisfy their own development without increasing the pressure on the local environment. Taking Guizhou Suiyang as an example, the solar power designed in the land application provides a solve the issue of power supply. low-carbon case study of underdeveloped areas to solve the issue of power supply.

Hall-Petch relation was widely applied to evaluate the grain size effect on mechanical properties of metallic material. However, the sample size effect on the Hall-Petch relation was always ignored. In the present study, the mechanical test and microstructure observation were performed to investigate the combined effects of grain and sample sizes on the deformation behaviors of gold microwires. The polycrystalline gold microwires with diameter of 16 ?m were annealed at temperatures from 100°C to 600°C, leading to different ratios(t/d) of wire diameter(t) to grain size(d) from 0.9 to 16.7. When the t/d was lower than 10, the yield stress dropped fast and deviated from the Hall-Petch relation. The free-surface grains played key role in the yield stress softening, and the volume fraction of free-surface grains increased with the t/d decreasing. Furthermore, the effects of t/d on work-hardening behaviors and fracture modes were also studied. With t/d value decreasing from 17 to 3.4, the samples exhibited necking fracture and the dislocation pile-ups induced work-hardening stage was gradually *** the t/d value further decreasing(t/d commonly applied in the packaging of integrated circuit chips, and the fabrication of microwire suffers multi-pass cold-drawing and annealing treatments to control the grain size. The present study could provide instructive suggestion for gold microwire fabrication and bonding processes.

Smart phones have become one of major electronic devices for human being. The easy and rapid exchange of information between man and machine is carried out by the touch screen panel (TSP) installed in the smart phones. Currently the smart phones are widely spread out while displays for automobiles are in the initial stage of developments. Since the automobile displays should fit the curved area of indoor space of the vehicle, the TSPs for automobiles need to be fabricated on the flexible and stretchable substrate film. In this study, we selected the thermo-plastic polyurethane film as the substrate film and examined the materials and process for fabrication of metal mesh type transparent conducting electrode films suitable for TSPs of automobile displays. The optimum UV resin system was established by the evaluation of various UV resin formulations in the UV imprinting process to make 3 × 3.5 μm trench patterns on the metal mesh type electrode film utilizing the embossed metal mask plate. The Ag paste has also been prepared by synthesis of Ag nanoparticles and formulation with the binder polymers. The inlay (filling) of Ag paste in the trench layer of transparent electrode film showed that the variation of electrical resistance was within 10% upon bending up to 100,000 times to radius of 3 mm.
