The aim of this study was to investigate in how far the way the specimen is fixed to the testing device influences the micro-tensile bond strength of adhesives to dentin. Compared to a flat jig, a notched jig enables the specimen to be aligned easier and more accurately perpendicular to the interface, thereby concentrating better the tensile stress at the actual interface. A notched jig yielded...

─ In this study, we present an UltraWideband (UWB) monopole antenna with bandnotched function. The proposed antenna is fed by a microstrip line. By using two modified forkshaped slots in the ground plane, bandwidth is increased that provides a wide usable fractional bandwidth of more than 135% (2.82-15.63). In order to achieve band-rejected performance, a cross-ring slot was inserted at the squ...

The toughness of bone is an important feature in preventing it from fracturing. We consider the notch sensitivity in impact, and the associations between brittleness, notch sensitivity and post-yield energy absorption of mammalian mineralized tissues. Specimens of bone-like tissues covering a wide range of mineralization were broken, either notched or un-notched, in impact. The greater the mine...

In this paper, a compact notched ultra-wideband (UWB) bandpass filter with improved out-of-band performance using quasi electromagnetic bandgap (EBG) structure is proposed. Firstly, a UWB bandpass filter based on a stepped-impedance stub-loaded resonator (SISLR) is combined with quasi-EBG structures, which suppress the undesired spurious bands to improve the out-of-band performance. In order to...

In this paper Cobalt-Chromium-Molybdenum (Co-Cr-Mo) specimens produced by Selective Laser Melting (SLM) for biomedical field were studied. particular, fatigue tests carried out comparing as-built condition with Hot Isostatic Pressing (HIP) and a heat treatment under vacuum condition. The influence on microstructure properties was investigated plain V-notched geometry. Both HIP had effects the i...

We discuss some problems of lattice tiling via Harmonic Analysis methods. We consider lattice tilings of R by the unit cube in relation to the Minkowski Conjecture (now a theorem of Hajós) and give a new equivalent form of Hajós’s theorem. We also consider “notched cubes” (a cube from which a reactangle has been removed from one of the corners) and show that they admit lattice tilings. This has...

Orthotropic steel deck (OSD) is applied on many bridges around the world, but its drawback of being prone to fatigue has been a concern due damages observed. Fatigue cracks initiated from blunt notch details in rib-to-floor beam connections have different behavior compared welded and deserve be investigated further. To study effect radius performance detail, 27 specimens with geometries were ma...

Weld residual stress and fracture behavior of 316L electron beam weldments, which are particular interest in power generation industry, were investigated this work. Two butt-weld joints manufactured stainless steel plates 6 mm 25.4 thicknesses. Three complementary methods used to measure the three orthogonal components weld coupons, tests conducted on single edge notched bending specimens extra...

Alumina toughened zirconia (ATZ) nanoceramics accompanied with high-strength, high-toughness and high-hardness were prepared by in-situ nanoprecipitation from using solid solution micro-powders. The submicron-sized Al2O3 (∼445 nm) ZrO2 (∼361 grains contained low-density precipitated nano-ZrO2 (∼35 nano-Y4Al2O9 (YAM, ∼87 particles, respectively, making high-performance nano-ATZ ceramics ultrafin...
