As one of the candidates low-temperature cofired ceramics (LTCC), sintering behavior, dielectric properties, and silver chemical compatibility NaCaVO4 were studied. The bulk ceramic samples densified well at a low temperature 720 oC with an optimal density 2.87 g/cm3. Excellent microwave properties relative permittivity εr ~ 9.9, high quality factor Q × f 31,600 GHz, coefficient resonance frequ...
The exploding growth of wireless communications systems leads to an increasing demand for integrated compact low-cost antennas. As a result, LTCC (Low Temperature Co-fired Ceramics) multilayer technology is becoming more and more popular for the production of highly integrated, complex multilayer modules and antennas. This technology is appreciated for its flexibility in realizing an arbitrary ...
As many emerging technologies require the use of high-speed signals, understanding dielectric properties materials used in manufacturing printed circuit boards (PCBs) is an essential aspect for accurate designs, especially at millimeter-wave (mm-wave) frequencies. This work demonstrates a methodology extracting complex relative permittivity substrates covering mm-wave For this purpose, low-temp...
A combination of field data and models have been used to estimate long-term carrying capacity (LTCC) domestic livestock in Queensland grazing lands. These methods synthesised coupled with recent developments science information technology provide a fully-automated approach modelling LTCC through the FORAGE online system. In this study, GRASP model was simulate pasture growth parameter sets safe...
In this paper, we present novel three-dimensional (3-D) compact and easy-to-design passive solutions (filters/duplexers, antennas, couplers) using system-on-package (SOP) multilayer low temperature cofired ceramic (LTCC) and organic (Liquid Crystal Polymer (LCP)) technologies in RF and millimeter-wave wireless systems. Both ceramic and organic technologies are candidates for the 3-D integration...
Low temperature co-fired ceramic (LTCC) with silver and gold conductor systems offer a low cost, high performance, and high reliability solution utilizing the advantages of ceramic technology. Gold conductors are generally used in applications requiring best reliability in harsh environmental conditions. Gold conductors are bonded to active or passive components through wirebonding, soldering, ...
BACKGROUND L-type calcium channel (LTCC) mutations have been associated with Brugada syndrome (BrS), short QT (SQT) syndrome, and Timothy syndrome (LQT8). Little is known about the extent to which LTCC mutations contribute to the J-wave syndromes associated with sudden cardiac death. OBJECTIVE The purpose of this study was to identify mutations in the α1, β2, and α2δ subunits of LTCC (Ca(v)1....
Short description Simplified mathematical models of some large-scale atmospheric and oceanic flow features will be presented, using geophysical fluid dynamics. Syllabus This course is about aspects of geophysical fluid dynamics, relevant to the climate system. The flows to be considered will be large-scale oceanic and atmospheric features. With the aim of constructing simplified idealised model...
The paper is focused on the micro-channel in LTCC (Low Temperature Co-fired Ceramics), which is one of the methods used for the creation of a fluid sensor. The sensor is composed of a mechanical and electrical part. The mechanical part is 3D structure, where are particular layers lamination on itself. There are many shapes, which creation results micro-channel after lamination and sintering. Th...
Wang W, Zhang H, Gao H, Kubo H, Berretta RM, Chen X, Houser SR. 1-Adrenergic receptor activation induces mouse cardiac myocyte death through both L-type calcium channeldependent and -independent pathways. Am J Physiol Heart Circ Physiol 299: H322–H331, 2010. First published May 21, 2010; doi:10.1152/ajpheart.00392.2010.—Cardiac diseases persistently increase the contractility demands of cardiac...
