Box 1254, Clausthal-Zellerfeld, D-38670, Germany Abstract:In the mass concrete structure construction, the thermal insulation material and cooling pipe are important temperature control materials to prevent concrete from cracking. In order to select the right materials, their heat exchange coefficients should be obtained exactly. But no proper apparatus can give the parameters through simple measure. An experiment concrete block with the dimension of 50m long and 22m wide was established near a dam construction site and the corresponding inversion calculating was applied. The experiment method is presented. The measured curves and calculated curves meet well which shows the inversed parameters reliable. Then the heat exchange coefficients of the EPE insulation materials with different thickness and the HDPE pipes with different diameters are given. The application effect shows the selected materials have achieved the goal of crack prevention. The experiment and inversion method will provide reference to other cases and the heat exchange coefficients can be used in similar structures. © (2011) Trans Tech Publications, Switzerland.

Box 3337, Columbus, OH 43210-3337, United States Abstract:1-Octyl amine was covalently coupled to sodium alginate(NaAlg) in an aqueous-phase reaction via acidamide functions using 1-ethyl-3-(3- dimethylaminopropyl) carbodiimide hydrochloride (EDC-HCl) as a coupling reagent to provide octyl-grafted amphiphilic alginate-amide derivative(OAAD) for subsequent use in λ-cyhalothrin (LCH) microcapsule application. The structure of OAAD was confirmed by FT-IR and 1H NMR spectroscopies. The new alginate-amide derivative was used for fabricating microcapsule that can effectively encapsulate LCH by emulsification-gelation technique. The microcapsules were characterized by optical microscopy (OM), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and laser particle size analysis. The encapsulation efficiency and drug release behavior of LCH from the microcapsules were investigated. Results showed that the microcapsules were in spherical form with diameter mostly in the range of 0.5-10 μm and possessed a structure with LCH as core and OAAD as shell. The encapsulation efficiency and the release performance of the microcapsules were influenced by DS of OAAD and amount of CaCl Number of references:21 Main heading:Encapsulation Controlled terms:Alginate - Amides - Calcium chloride - Coagulation - Emulsification - Gelation - Hydrogels - Nuclear magnetic resonance spectroscopy - Optical microscopy - Particle size analysis - Scanning electron microscopy - Sodium - Synthesis (chemical) - Transmission electron microscopy Uncontrolled terms:Acidamide - Amphiphilics - Carbodiimide hydrochlorides - Coupling reagents - Drug release - Encapsulation efficiency - H NMR spectroscopy - Laser particle size analysis - Microcapsules - Release performance - Sodium alginates Classification code:951 Materials Science - 932.2 Nuclear Physics - 813.2 Coating Materials - 804 Chemical Products Generally - 802.3 Chemical Operations - 802.2 Chemical Reactions - 741.3 Optical Devices and Systems - 741.1 Light/Optics - 549.1 Alkali Metals DOI:10.1021/bm200571k Database:Compendex Compilation and indexing terms, Copyright 2011 Elsevier Inc.

(AOCABFE); Shandong Agricultural Machinery Society Publisher:IEEE Computer Society, 445 Hoes Lane - P.O.Box 1331, Piscataway, NJ 08855-1331, United States Abstract:A field experiment was conducted to study prediction models of rice transpiration intensity at three different growth stages (including jointing booting, heading to flowering and milk stage) at none-water layer. Correlation analysis and stepping multi-regression analysis suggested that soil moisture content of root zone, temperature in the field, relative humidity and wind speed were the four main factors affecting the transpiration intensity of semilate rice. Error analysis also showed that the multi-linear regression models of transpiration established based on soil moisture content and major meteorological factors at three different growth stages were satisfying, and the maximum relative errors are 4.39%, 1.71% and 2.81% respectively. Research results establish a basis for the calculation of semilate rice water requirement at none-water layer of paddy. © 2011 IEEE.

A simple, physically based model would be more useful than the complex two-phase (gaseous and liquid phase) flow model to describe water infiltration in layered soils with air entrapment.

A layered model with interacting networks can facilitate the description and analysis of such systems. In this paper we propose a model of traffic dynamics and reveal a transition at the onset of cooperation between layered networks. The cooperation strength, treated as an order parameter, changes from zero to positive at the transition point. Numerical results on artificial networks as well as two real networks, Chinese and European railway-airline transportation networks, agree well with our analysis. © 2011 American Physical Society.
