The L-type calcium channel (LTCC) provides trigger Ca(2+) for sarcoplasmic reticulum Ca-release, and LTCC function is influenced by interacting proteins including the LTCC distal COOH terminus (DCT) and calmodulin. DCT is proteolytically cleaved and reassociates with the LTCC complex to regulate calcium channel function. DCT reduces LTCC barium current (I(Ba,L)) in reconstituted channel complex...

Multilayer LTCC substrates with screen printed conductors are considered as a key technology for coming RF wireless communication and automotive applications. The direct integration of passive components inside the LTCC environment strongly reduces the costs of a multichip module (MCM). The aim of this paper is to present an efficient way to design a band pass filter for 25GHz with regard to th...

The electrical and microstructural characteristics of 1 kX/sq. thick-film thermistors with high positive temperature coefficients of resistivity, i.e. PTC 5093 (Du Pont) fired either on ‘‘green’’ LTCC (low temperature cofired ceramics) substrates or buried within LTCC structures, were evaluated. The active phase (ruthenium oxide) in the PTC thermistors is not present in the dried films but is f...

In this paper, a study of the power and impulse frequency influences on the microfabrication fluidic structures by infra-red laser ablation in low-temperature co-fired ceramics (LTCC) substrates is presented.LTCC technology , which has been commonly used for electronic applications, is presented as a useful alternative to construct continuous flow analytical microsystems. A μ-FFE device, with e...

A miniature electrostatic thruster is being developed in Low Temperature Co-fired Ceramic (LTCC) at Boise State University. The thruster is composed of an antenna to create the plasma, a cylinder to contain the plasma, and grids to extract the plasma beam at high velocity. In this work, the development of the inductively coupled plasma (ICP) antenna in LTCC will be presented. This antenna is fa...

BACKGROUND Obstructive Lung Diseases (OLDs), could lead to progressive hyperinflation of the lungs that cause increased work of breathing, impaired gas exchanges and functional limitations in patients. In this study, thoracic circumference of patients in upper and lower third were measured directly and the association of the upper to lower third width of chest with spirometric parameters was ev...

OBJECTIVE Contraction of cardiac myocytes is initiated by Ca(2+) entry through the voltage-dependent L-type Ca(2+) channel (LTCC). Previous studies have shown that phosphatidylinositol (PI) 3-kinase signaling modulates LTCC function. Because PI 3-kinases are key mediators of insulin action, we investigated whether LTCC function is affected in diabetic animals due to reduced PI 3-kinase signalin...

High temperature XRD has been employed to monitor the devitrification of DuPont 951 low temperature co-fued ceramic (LTCC) and DuPont ES4005 resistor ink. The LTCC underwent devitrification to an anorthite phase in the range of 835-875 ‘C with activation energy of 180 kJ/mol as calculated from kinetic data. The resistor paste underwent devitrification in the 835875 ‘C range forming monoclinic a...

L-type calcium channel (LTCC) function is critical for electrical and cellular signaling in a diverse range of cell types. In cardiac muscle LTCC function (I Ca,L) provides trigger Ca 2+ for Ca2+-induced Ca release, and ICa,L kinetics is a critical determinant of action potential duration.1 LTCC blockade is an effective antihypertensive regimen, likely owing to contributions of ICa,L in vascula...

Using LTCC (Low temperature co-fired ceramics) system in wireless packaging applications is wide used today. The properties requirements for wireless applications are requiring low loss at high frequencies and good characteristic comparative to cost. Several designs of packaging systems are presented in various microwave packaging applications such antenna. The relative curves of dielectric con...
