An approach to producing hierarchical multi-scale porous ultra-high temperature ceramics (zirconium diboride, ZrB2) using 3D printing has been developed. Porous ceramic filaments can be printed via Direct Ink Writing (DIW) (paste extrusion). Millimeter scale porosity is created by the scaffold filaments. We introduce 20-micron-scale into with addition of oil produce capillary suspension paste i...

In the absence of suitable deposition processes, the fabrication of graded-index chalcogenide waveguides or fibers remains an outstanding challenge. Here, by exploiting the strong thermo-optic effect present in chalcogenide glasses, we experimentally demonstrate non-permanent optically-induced waveguides in bulk As2Se3 rods using a 1.55 μm wavelength laser. This single-ste...

The prevalence of musculoskeletal issues in clinical practice, and the limited focus placed upon musculoskeletal conditions by current electronic summary resources, highlights the need for a resource that provides access to simple and concise summaries of top-quality orthopedic literature for orthopedic surgeons and allied healthcare professionals. OrthoEvidence™ is an online clinical resource ...

Enhanced p l a in TJ$ macros and a bidding environment for typesetting bridge card distributions and bidding sequences are given as a follow-up to the IPW macros given in [12]. Moreover, macros for annotated printing of the course of the play are provided. Examples of use are included.

OBJECTIVE To assess students' opinion regarding the application of Epidemiology, Biostatistics and Survey Methodology courses in medical research. METHODS A cross-sectional study was conducted to assess the opinion of the third and fourth year students regarding the relevance of Epidemiology, Biostatistics and Survey Methodology courses, which are taught in the first two years, to medical res...

E-beam lithography has been used for reliable and versatile fabrication of sub-15 nm single-crystal gold nanoarrays and led to convincing applications in nanotechnology. However, so far this technique was either too slow for centimeter to wafer-scale writing or fast enough with the so-called dot on the fly (DOTF) technique but not optimized for sub-15 nm dots dimension. This prevents use of thi...

background and aim: academic achievement, especially in hard-of-hearing students, is hinged on their writing skills, and writing skill deficiency can adversely affect their cross-disciplinary skills. the purpose of this study was to explore and delineate the writing skill curriculum for hearing-impaired students in primary school system of iran and to develop an exploratory model. methods: in t...
