The knowledge of liminology can be applied in studies of trophic state indexes and morfoedaphic indexes as factors for determining the inference fish production in reservoirs. This work is based on the hypothesis of the trophic cascade relations, particularly related to bottom-up and top-down effect in Itaipu Reservoir (Brazil). Using the data available by Itaipu, from 1999 to 2004, analyzes of multiple regressions were accomplished to determine the relationships of the dependent and independent variables. We applied the trophic state indices (TsI) based on readings secchi disk, total phosphorus and chlorophyll-a density for obtaining TsI medium. Morfoedaphic index was calculated based on the reading of the concentration of dissolved solids and the inference of fishing yield, from this index. The average results of the trophic state indices indicate an oligotrophic status for the entire reservoir as well as for the riverine, transition and lacustrine zones separately. The fish was yieldn Estimated by the relation with cyanobacteria concentration, and this was the best variable que explained this prediction. The use of the morfoedaphic index (MEI), with the recorded catch data, predictive models can generate que estimate the fishing yield in the Itaipu Reservoir. The relations of MEI with chlorophyll-a and water transparency que Indicate this index may be a good predicting factor for future fish captures.

Commercial coal production in the southern region of Brazil (comprising the paraná, santa Catarina, and Rio Grande do sul states) has been occurring since the beginning of the twentieth century. Regarding the santa Catarina coalfields, about 60% - 65% of the ROM coal is discharged at dump deposits as waste. These wastes can lead to the formation of acid mine drainage (AMD), a source of ground and surface water pollution. One of the technologies used for preventing AMD consists of the alkaline additive method. Thus, the aim of this work was to study, at laboratory scale, the DAM control by blending coal waste with a metallurgical slag. A coal-tailing sample was collected from a coal mine, and the slag was obtained from a semi-integrated steel plant. static tests were carried out by the acid-base account method to determine the balance between the acid-producing and acid-consuming (neutralizing) mineral components of the samples. Kinetic tests were conducted in humidity cells, following the AsTM D 5744-96 method, for a period of 80 weeks. The results showed that the coal tailing generates AMD. However, environmental problems can be minimized by mixing the coal waste with the metallurgical slag in 1:1 or 1:1.5 proportions. The kinetic experiments proved that, in this condition, the lixiviation presents a higher pH and a lower concentration of acidity, metals, and sulfate. Finally, it is possible to conclude that the blending slag in coal tailing deposits can be a viable alternative for DAM control in coal mining.

再生高强铝合金由于力学性能差,在结构材料方面的应用有限。喷射成形重熔后再热挤压是一种有前途的用于7系铝合金的再加工方法。对7050铝合金切屑进行喷射成形、热挤压、旋锻和热处理,以恢复其力学性能。制备直径2.7mm的再生铝合金线材,研究其显微组织、拉伸性能和疲劳强度。采用XRD、sem、EBsD、Tem和DsC等手段对二次相和析出相进行表征。对比锻态和热处理(固溶和时效处理)态合金线材的力学性能,发现两种合金线材的力学性能均优于AA7050航空规范。材料在旋锻过程中发生大量的塑性变形,从而导致急剧的晶粒细化,可观察到细小的微观和亚微观Al晶粒、粗大和细小的金属间化合物析出相。随后的固溶处理导致形成均匀的再结晶和等轴晶(9μm)显微组织。在120℃时效处理后,形成纳米级Gp(I)区和η′析出相,合金表现出更高的抗拉强度(586 Mpa)和疲劳强度(198 Mpa)。

3D photo-Fabrication for Tissue Engineering and Drug delivery

引用

Engineering 2015年第1期1卷 90-112页

作者： Rúben F.pereira paulo J.Bártolo Centre for Rapid and sustainable product development (CDRsp) Polytechnic Institute of Leiria Instituto de Investiga??o e Inova??o em saúde (I3s) Universidade do Porto Instituto Nacional de engenharia Biomédica (INEB) Universidade do Porto Instituto de Ciências Biomédicas Abel salazar (ICBAs) Universidade do Porto school of Mechanical Aerospace and Civil EngineeringUniversity of Manchester Manchester Institute of Biotechnology University of Manchester

The most promising strategies in tissue engineering involve the integration of a triad of biomaterials, living cells, and biologically active molecules to engineer synthetic environments that closely mimic the healing milieu present in human tissues, and that stimulate tissue repair and regeneration. To be clinically effective, these environments must replicate, as closely as possible, the main characteristics of the native extracellular matrix(ECM) on a cellular and subcellular scale. photo-fabrication techniques have already been used to generate 3D environments with precise architectures and heterogeneous composition, through a multi-layer procedure involving the selective photocrosslinking reaction of a light-sensitive prepolymer. Cells and therapeutic molecules can be included in the initial hydrogel precursor solution, and processed into 3D constructs. Recently, photofabrication has also been explored to dynamically modulate hydrogel features in real time, providing enhanced control of cell fate and delivery of bioactive compounds. This paper focuses on the use of 3D photo-fabrication techniques to produce advanced constructs for tissue regeneration and drug delivery applications. state-of-the-art photo-fabrication techniques are described, with emphasis on the operating principles and biofabrication strategies to create spatially controlled patterns of cells and bioactive factors. Considering its fast processing, spatiotemporal control, high resolution, and accuracy, photo-fabrication is assuming a critical role in the design of sophisticated 3D constructs. This technology is capable of providing appropriate environments for tissue regeneration, and regulating the spatiotemporal delivery of therapeutics.
