Spider silk is a material of extraordinary beauty and utility. From the spider's perspective, it is foremost a building material, but also a safety net, a sensory organ, a weapon. From a human perspective, it is a material of extraordinary mechanical properties, an object of artistic and cultural interest, and a valuable window into the evolutionary history of spiders. Historically, there have been a mere handful of spider silk textiles, the most recent example of which was constructed by Simon Peers and Nicholas Godley. This was an extravagant work of art, and the silk was collected entirely by hand. Though the finished article is a testament to the beauty of spider silk, it also illustrates the technical challenges associated with obtaining it in any significant quantity. The effects of this scarcity are evident in the lab of David Kaplan at Tufts University. His group has developed a wide variety of applications for silk, but has focused mainly on silkworm silk in spite of spider silk's greater variety and superior mechanical properties. In the wild, spiders use silk for everything from weaving webs and capturing prey to breathing underwater. Shaped by almost every environment on Earth, spider silk has evolved into endless variations and permutations, offering a vast wealth of material knowledge if we can find a way to tap it. A visit to Cheryl Hayashi's spider silk genetics lab at the University of California, Riverside offers a look inside a spider and a glimpse of how genetic research can illuminate the evolution of silk. At the same time, it puts the limits of our knowledge into stark relief. The scarcity of natural spider silk has helped to drive a small industry in bioengineered and synthetic silk research, and also motivated projects that seek to apply the structural principles of silk fibers to other materials. But so far, these efforts are only a pale imitation of the real thing. For now, the spider is keeping her secrets.

Full textThe purpose of this research has been to examine possible factors which effect yarn production and prices in the U.S.The research approach first involved gathering the data from different sources about yarn production and prices. Second, data was gathered about the different factors which could have an effect on these. These factors included enduse demand, cotton consumption, the effect of spinning systems, labor cost and demand, machinery hours and shipments, and the level of imports and exports. Third, the data was compared and conclusions were made based solely on the obvious trends in the data. Fourth, current situations in the textile market were examined in order to conclude if any have had an effect on yarn production and price. The main issues which are facing the textile industry and were included in this analysis were NAFTA, CBI, Asia and the WTO. The effect that these have had and will have on the spinning industry was examined in detail. Fifth, a statistical analysis was conducted. The analysis included the use of a correlation matrix for both yarn production levels and yarn prices in order to see which factors statistically had the strongest impact on these. Overall, this research offers a view into the inside of the U.S. spinning industry, including the dynamics which effect final yarn production levels and yarn prices, as well as situations which will have an impact on the future of the spinning industry.

Full textSilk fibers from arthropods possess several favorable properties for biomedical applications, including high mechanical strength and biocompatibility. However, the majority of silk fiber production is currently limited to manipulation of cocoons from the Bombyxmori silkworm. The efficiency of the process can be increased by dissolving waste silk threads and using artificial spinning techniques to spin the proteins back into usable fibers. Once an artificial spinning technique has been perfected, it may be possible to use similar designs to spin recombinant silk proteins into threads with more favorable mechanical properties. The first step towards customizable silk is to artificially spin silk protein into fibers with comparable properties to naturally-derived silk threads. Current microfluidic devices are limited to spinning B. mori silk into weak, poorly-formed fibers. The incorporation of silk gland-like ion gradients and high shear stress into current and novel microfluidic devices is theorized to improve mechanical properties of resultant spun silk. To this end, ion gradients were added to the current microfluidic device. In addition, a novel microfluidic device was developed to increase shear stress. After investigating the individual effects of ion gradients and shear stress on the silk spinning process, an integrated microfluidic device was designed to investigate the combined effects. Computational models of the flow within each microfluidic device were generated and used to predict biomimetic design parameters. Measurements of fiber diameter and pH within the microfluidic devices were collected to verify the accuracy of the computational models. Attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and mechanical testing measurements were collected to characterize and compare resultant fibers. From these results, relationships were found between the incorporation of ion gradients and shear stress into the spinning process and the properties of the fibers produced.

Full textEste trabalho trata das metodologias disponíveis mais utilizadas para a avaliação da reserva girante em sistemas de potência. São apresentadas abordagens determinísticas e probabilísticas. Uma grande variedade de aspectos são considerados e organizados de modo a se obter uma taxionomia metodológica. A aplicação da taxionomia sugerida é ilustrada com a análise de um sistema hipotético, o IEEE Reliability Test System, e do sistema brasileiro das regiões Sul/Sudeste/Centro-Oeste. Com base nos resultados obtidos com a aplicação de tal taxionomia à metodologia atualmente utilizada no Brasil, são apontados aspectos que necessitam de maiores pesquisas. Uma das principais conclusões obtidas revela que a prática atual de se associar os períodos críticos de risco àqueles de maior capacidade em manutenção não possui respaldo prático nem teórico.
This report reviews the most representative techniques currency available for power systems spinning reserve evaluation. Both deterministic and probabilistic approaches are tackled. A broad range of aspects are considered and organized in a practical methodological taxonomy. The application of the suggested taxonomy is illustrated with the aid of hypothetical systems, the IEEE Reliability Test System, and the Brazilian South/Southeast/Midwest System. Based on the diagnosis resulting from the application of the taxonomy to the methodology currently utilized in Brazil, several aspects in need of improvement are pointed out. As one of the main results attained, it shown that, the current practice of considering the critical risk period as coincident with the critical maintenance period, lacks practical evidence and theoretical support.

Full textMost of our understanding of metalloproteins derives from atomic or molecular structures obtained from diffraction methods on single crystal samples. However, not all proteins are amenable for diffraction studies, and even when a highly-resolved structure is available, often the nature of the metal ion, its coordination geometry or its oxidation state are not determined. The aim of the present thesis is the investigation of structural properties of metal sites in paramagnetic metalloproteins by Magic-Angle Spinning Nuclear Magnetic Resonance (MAS NMR). MAS NMR is a powerful technique for the investigation of biological systems, and may represent a direct probe of the structure at the active site of paramagnetic metalloproteins. However, it suffers from limited sensitivity and resolution when applied to nuclei close to a paramagnetic center.In this thesis, we address these limitations by developing NMR methods based on ultra-fast (60-111 kHz) MAS rates. A “toolkit” of suitably designed pulse sequences is built for the detection and the assignment of nuclei in close proximity of a paramagnetic center. State-of-the-art computational techniques are also employed to convert the experimental data into structural restraints for obtaining atomic-resolution geometries of active sites. We benchmark this approach with the study of Fe, Cu and Co sites in two microcrystalline proteins, and we also provide preliminary data on a non-diffracting divalent metal ion transporter in lipid membranes. We anticipate that the techniques described here are an essential tool to elucidate many currently unanswered questions about structure and function of metal sites in structural biology

Full textThe Southern Nylon Spinning plant, at South African Nylon Spinners in Bellville - Cape Town - South Africa, is one of the oldest on the site and a need arose to upgrade the existing method used in speed monitoring in this particular plant. This system was unable to produce alarms on speed limits being exceeded (i.e. on under-speed or over-speed). There was no alarm logging or historical trending. Manual records on speed were either incomplete or non-existent. Thus the purpose of this study was to investigate the existing speed monitoring system and implement a suitable computerised method of speed monitoring.

Full textWhen the tether has high nominal tension, averaging with two variables results in a closed form solution, which shows dependence of the frequency contents on the initial amplitude parameters of the system. In the case of very low nominal tension, averaging with a single variable is useful to obtain the steady state and the limit steady state solutions, both of which result in a circular whirling motion like a skip-rope. Without damping, a general transverse mode appears to be quasi-periodic but it can be periodic under certain initial conditions. Numerical investigations reveal that the material damping through the longitudinal mode derives the steady state to the limit steady state. Also, several interesting shapes are observed in phase plots.
