    Description / Table of Contents: This volume applies the science of complexity to study coupled human-environment systems (CHES) and integrates ideas from the social sciences of climate change into a study of rural development amid flooding and urbanization in the Poyang Lake Region (PLR) of China. Author Qing Tian operationalizes the concept of sustainability and provides useful scientific analyses for sustainable development in less developed rural areas that are vulnerable to climatic hazards. The book uses a new sustainability framework that is centered on the concept of well-being to study rural development in PLR. The PLR study includes three major analyses: (1) a regional assessment of human well-being; (2) an empirical analysis of rural livelihoods; and (3) an agent-based computer model used to explore future rural development. These analyses provide a meaningful view of human development in the Poyang Lake Region and illustrate some of the complex local- and macro-level processes that shape the livelihoods of rural households in the dynamic process of urbanization. They generate useful insights about how government policy might effectively improve the well-being of rural households and promote sustainable development amid social, economic, and environmental changes. This case study has broader implications. Rural populations in the developing world are disproportionally affected by extreme climate events and climate change. Furthermore, the livelihoods of rural households in the developing world are increasingly under the influences of macro-level forces amid urbanization and globalization. This case study demonstrates that rural development policies must consider broader development dynamics at the national (and even global) level, as well as specific local social and environmental contexts. By treating climate as one of many factors that affect development in such places, we can provide policy recommendations that synergistically promote development and reduce climatic impacts and therefore facilitate mainstreaming climate adaptation into development

    Notes: Initial attachment and spreading of the inoculated cells determines the long-time viabilityof cells onto biomedical scaffolds designed for various orthopedic or other clinical applications. Theaim of this study was to investigate the influence of biomimetic thin film coating surfaces ofbio-derived bone scaffolds with collagen proteins and chitosan on bone marrow mesenchymal stemcells interactions in order to improve cell adhesion, spreading and proliferation. These two meritswere used synthetically to generate apatite-based materials that can function as allograft bone graftsin humans. In this study, the thin film coatings were operated by means of soaked, pre-frozen, andfreeze-dried step by step. All coatings were characterized using Raman spectra, inverted microscope,atomic force microscopy, and scanning electron microscopy. After that, the bio-derived bonescaffolds with or without thin film coatings were used in bone marrow mesenchymal stem cell cultureexperiments to study cell adhesion, spreading, viability, proliferation and morphology. Then, thebiological morphologies of the fabricated cell-scaffold constructs were detected by scanning electronmicroscope (SEM). The cell reactions were investigated concerning cell adhesion, migration,spreading, and proliferation under inverted microscope and fluorescence microscopy. The resultsshowed that the bio-derived bone scaffold treated with thin film coatings by using rat-tail type Icollagen and chitosan improved the adhesion and spreading of mesenchymal stem cells incomparison to the untreated one. Besides, cell viability and morphology were not affected by thepresence of either type of thin film coating. Still, the results assay revealed an increased proliferationof bone marrow mesenchymal stem cells on both types of thin film coatings compared to coating withnon-coated controls

    Notes: The crystallization behaviors and microstructural developments in the CaO-MgO- Al2O3-SiO2glass with Fe2O3, ZrO2 and F as additives were investigated by using scanning electron microscopy, X-raydiffraction and differential scanning calorimetry techniques. In the glass sample with 1.0wt% Fe2O3, onlysurface crystallization were observed, in which a three-layer compound surface containing the finedendrite, finer fibrous morphology and particle-shaped crystals was formed respectively from the nearfree surface to the inner region. The crystalline phases precipitated were anorthite and wollastonite at1000°C, and diopside at 1040°C. The addition of ZrO2 suppressed the nucleation and growth of thecrystalline phases. The addition of another 4.0wt% fluorine into the glass with a pair of 1.0wt% Fe2O3 and2.0wt% ZrO2 induced the bulk crystallization, the surface and bulk crystallizations were both observed at1040°C. At the surface, a three-layer morphology, which had similar morphology to the glass with1.0wt% Fe2O3 was formed. In the bulk region, the block-shaped crystalline phases were precipitatedhomogeneously in the residual glass

    Notes: In this study, the surface modification and biocompatibility of the biologic chitosanscaffold were investigated. The chitosan scaffold with excellent reticular structure was attained afterbeing purified, emulsionized, cross-linked, molded and freeze-dried step by step by using the nativematerials, coming from such as lobster shell, crab shell etc.. After that, its surface modification wasoperated with film coating by using gelatin. Then the bone marrow mesenchymal stem cells (BMSCs)derived from New Zealand rabbits were used as the seed cells and were inoculated onto the modifiedbiologic chitosan scaffolds at 3×105 cells/ml to investigate the biocompatibility and bone conductiveefficiency of this kind of scaffold in static culture for one week. As a control, the cell suspensions withsame densities were inoculated onto the chitosan scaffold without being treated. During the wholeculture process, the cellular adherence and expansion were observed under inverted microscope.After culture, the biological properties of the fabricated cell-scaffold tissues were detected byscanning electron microscope (SEM) and HO/PI fluorescent double staining. The results showed thatthe biologic chitosan scaffold treated with gelatin or rat-tail collagen promoted a higher adhesion andproliferation of BMSCs in comparison to the untreated samples. Besides, the BMSCs within thetreated scaffold were more regular and well-distributed than those in untreated one. It is concludedthat this kind of surface modification can be used to change the physicochemical properties ofchitosan scaffold. The improved biologic chitosan scaffold is suitable to be an ideal biomedicalscaffold for tissue engineering

    Notes: Electrochemical measurement techniques were applied to investigate the polarization andhydrogen permeation behavior of Cu-bearing CrMo steel in a H2S saturated aqueous brine solution.The observation on microstructure and precipitate phases of the steel was conducted bytransmission electron microscopy (TEM), and the corrosion product was investigated by usingX-ray diffractometer (XRD), X-ray photoelectron spectroscopy (XPS), and scanning electronmicroscopy (SEM). It is disclosed that copper addition could effectively influence theelectrochemical behavior of the investigated steel, and the dissolution behavior of iron matrix andcarbide precipitates in the H2S solution acts as a key role for the steel resistance to hydrogen sulfidecorrosion

    Notes: The phase-separation and the crystallization of SiO2-MgO-Al2O3-K2O-Fe2O3-F glass wereinvestigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and electron probe ofmicroanalyzers (EPMA). The results reveal that the varieties and the morphology of crystalline phasesformed depend sensitively on the thermal treatment schedules. During the isothermal treatments, thecrystalline phases of mica, mica and iron oxide (FeFeO4), and FeFeO4 as major crystals are precipitated inthe glass samples heat-treated at 900, 1000 and 1050°C respectively. However, the two-step heattreatment beginning at 900°C for 1h and subsequently followed at 1050°C for 1h leads to the precipitationof mica crystal and no any signs of FeFeO4 crystalline phase is observed. Also the morphology of sampleis different from that of the isothermally treated glass at 1050°C, but is similar from that of sample at900°C. A “worm”-shaped phase-separation is observed in the sample heated at 800°C for 0.5h, whichexhibits different morphology from that of droplet- or globule-shape conventionally discerned. EPMAresults show that the incorporation of Fe2O3 accelerates accumulation of fluorine element, promoting thephase-separation and the crystallization of the present glass

    Notes: It is very possible for the foam zinc materials to take the place of zinc powder and becomea new ideal material of electrode for zinc-air battery, because of its excellent three dimensionalreticulated structure, high porosity, high specific surface area and uniform quality, and was widelyused in many other fields. A novel method for preparing very porous zinc foam was proposed, inwhich the polyurethane foam as substrate was processed by degreasing process, roughening process,activation, electroless plating and zinc electrodeposition. Then, experiments were carried out toexplore the effects of the solution composition(concentration of ZnSO4)and the operation conditions (such as the interelectrode distance; current density, temperature, pH value of electroplatingsolution and so on) on the morphology of the foam zinc and the current efficiency. The optimumexperimental conditions were determined by optimizing the factors. On these conditions the foamzinc presents a three-dimensional reticular structure with high porosity, and uniformity, and theoutward appearance of the coating is bright
