Student nations or simply nations are regional corporations of students at a university. Once widespread across Europe in medieval times, they are now largely restricted to the ancient universities of Sweden and Finland. The students, who were all born within the same region, usually spoke the same language, and expected to be ruled by their own familiar law. The most similar comparison in the Anglo-world to the nation system is in the collegiate system of older British universities or fraternities at American universities; however, both of these comparisons are imperfect. In Portugal and Brazil, there are fraternities called Repúblicas, but this has nothing to do with the natio original concept of nations . Wikipedia.

This study presents a parylene-based trench isolation (PBTI) method using standard silicon wafer to obtain a suspended MEMS structure. The silicon-based suspended structures were electrically isolated using supported parylene beams. The parylene beams provide electrical isolation between the suspended structure and substrate, and prevent anchor movement during actuation and wire-bonding. The proposed process is a simple low-temperature, dry-etching and reliable fabrication method for structure creation and electrical isolation and does not require wet-release, LPCVD, plasma-enhanced chemical vapor deposition (PECVD), ion implantation, sputtering process, or sandwiched oxide/polysilicon/metal isolation. The parylene beams were created by performing multiple steps of parylene deposition and removal inside a silicon mold. The trench etching, polymer deposition for sidewall protection, floor polymer removal, structure release, and polymer stripping steps were completed by modifying the etching or passivation steps of the Bosch process. These steps can be integrated into a single-run ICP process controlled by macro commands; the ICP etcher can automatically complete suspended structure creation in a single run. A test device with a thickness of 50 μm and a maximum trench aspect ratio of 10 was created to demonstrate process feasibility. The proposed process can be used for sensors and actuators, requiring a considerable device thickness to enhance sensitivity and performance. The test device is a comb-drive like device used to check the electrical isolation for sensor and actuator. Design, simulation, and fabrication considerations are discussed. © 2017, International Journal of Automation and Smart Technology.

Thin Solid Films | Year: 2011

Inorganic-solid-state electrolyte tantalum oxide thin films were deposited by reactive DC magnetron sputtering to improve the leakage and deterioration of traditional liquid electrolytes in electrochromic devices. O2 at 1-20 sccm flow rates was used to deposit the tantalum oxide films with various compositions and microstructures. The results indicate that the tantalum oxide thin films were amorphous, near-stoichiometric, porous with a loose fibrous structure, and highly transparent. The maximum charge capacity was obtained at an oxygen flow rate of 3 sccm and 50 W. The transmission change of the Ta 2O5 film deposited on a WO3/ITO/glass substrate between colored and bleached states at a wavelength of 550 nm was 56.7%. The all-solid-state electrochromic device was fabricated as a multilayer structure of glass/ITO/WO3/Ta2O5/NiOx/ITO/ glass. The optical transmittance difference of the device increased with increasing applied voltage. The maximum change was 66.5% at an applied voltage of ± 5 V. © 2011 Elsevier B.V.


The invention provides an evaluation method capable of objectively evaluating average visual perception for a comparatively long period of time when a subject looks through an eyeglass lens to be evaluated, time-dependent change in visual perception, and visual perception when looking with both eyes, and the invention provides a design method, and the invention provides a calculation method for calculating characteristics of visual perception of the subject when viewing an object through a lens. [Solution] A subject is allowed to wear a lens to be evaluated, the subject is allowed to induce brain activity by allowing the subject to view a changing visual stimulus object that induces periodic brain activity through the lens to be evaluated, a change in faint electric current caused by the brain activity is time-dependently recorded as a change in a magnetic field (magnetic flux density) by use of a magnetoencephalograph, one or more among an amplitude, a power value, and a phase in a frequency that is an inverse number of a period of the periodic brain activity is or are calculated through fast Fourier analysis of the waveform, and the lens to be evaluated and the characteristic of visual perception of the subject are evaluated based on a magnitude of an amplitude or of a power value obtained above or based on a slowness/fastness of a phase obtained above.

As is well known in biology, organisms adapt and evolve in response to their surrounding environments, a phenomenon similarly found in product development. Among the factors that may influence product changes include functional improvements, consumer habits, and the emergence of new technologies. Humans must develop products that impact the environment minimally to ensure sustainable living. This work presents a forecasting novel model to acquire innovative ideas more easily to design eco products, followed by evaluation of whether the new design is more effective than currently available ones in the concept design stage. The innovative approach to solving design problems is based on TRIZ evolution patterns, in which the index system of case-based reasoning connects the innovative idea to cases located in a database to accelerate the process. Finally, simple life cycle assessment is introduced to determine whether if the solution is better for the environment than the currently available ones. A novel eco-innovation concept for a cell phone is also presented to demonstrate the effectiveness of the proposed model. © 2011 Elsevier Ltd. All rights reserved.

Purpose: The purpose of this study was to determine the success rate of the distraction arthrodesis, which was attempted to maintain the limb length during arthrodesis using an intramedullary nail and mixed bone grafting, in terms of the eradication of infection, solid union, and functional outcome. The hypothesis was that distraction arthrodesis would be successful in union and elimination of infection with minimal limb shortening and a satisfactory functional outcome despite large bone defects. Methods: Eight patients were managed by arthrodesis using a Huckstep intramedullary nail and massive corticocancellous bone chip grafts from autologous iliac bone and deep-frozen femoral head allografts were included in the study. The mean age of the patients was 65. 5 ± 7. 1 years, and the follow-up duration was 52. 1 ± 21. 3 months. A mean of 5. 3 ± 1. 3 surgical procedures had been performed before arthrodesis. The mean longest and shortest distances of the bone defect were 58. 6 ± 10. 3 and 34. 6 ± 7. 0 mm, respectively. Results: Radiological union was obtained in all cases at a mean of 9. 9 ± 1. 9 months. The mean postoperative limb shortening was 11. 0 ± 7. 3 mm when compared to the contralateral knee. The mean Knee Society score was 59. 9 ± 9. 2, and the function score was 38. 8 ± 13. 3. No additional procedures were required for any of the patients. Conclusion: Distraction arthrodesis of infected knees following total knee arthroplasty demonstrated union and eradication of infection in all patients and a large tibiofemoral gap due to the severe bone defect could be managed with massive bone chip grafts. This method of arthrodesis would be a reliable and an effective method for failed total knee arthroplasty when two-staged reimplantation fails or is not attainable.
