Formation of tooth enamel is a very complex process in which specific set proteins secreted by ameloblasts play primordial role. As part screening procedure to identify novel EO (enamel organ) cells rat incisors, we isolated partial cDNA fragment (EO-017) that the homologue recently described mouse Amtn (amelotin) gene [Iwasaki, Bajenova, Somogyi-Ganss, Miller, Nguyen, Nourkeyhani, Gao, Wendel and Ganss (2005) J.

The primary source of divided government in the United States is voters who split their ballots between parties. Yet there has been little comprehensive examination either patterns or sources ticket splitting recent years. Instead, divergent lines research have emerged, emphasizing such things as voter partisanship, incumbency, and a “new” (young, well-educated, even partisan) kind splitter; focus too often restricted to atypical president–Congress pair. We seek unify these traditions model...

A wideband aperture coupled flipped staired pyramid shaped DRA is presented. An impedance bandwidth of 62% (S11<−10 dB) measured. The proposed has a stable broadside radiation pattern across the matching band, with an average gain 6.5 dBi. Simulation results obtained from Fidelity give good agreement measured results.

Improvements for permittivity measurements with short, open-ended coaxial line probes are achieved by using a more accurate formulation and adding finite conductor flange at the aperture of probe. A diameter about 10 times outer greatly improves performance For probe without flange, three-term admittance formula calculated coefficients gives good measured results as compared to standards. However, two-term calibration coefficient better results.< <ETX...

Political scientists have developed increasingly sophisticated understandings of the influences on Supreme Court decision making. Yet, much less attention has been paid to empirical measures Court's ideological output. We develop a theory interactions between rational litigants, lower court judges, and justices. argue that most common measure output—whether is liberal or conservative—suffers from systematic bias. trace this bias empirically explain undesirable consequences it for analyses...

Antenna designs are achieved for wideband operation by the use of a coplanar patch-slot antenna, fed waveguide. This design is easily tuned to operate at 2.45 and 5.75 GHz, with wide bandwidth wireless systems. The operating frequency controlled modifying patch dimensions. return loss, input impedance, radiation pattern, directivity, gain, efficiency proposed computed presented. A parametric study antenna also introduced.

Abstract Political leaders’ willingness to use force is central many explanations of foreign policy and interstate conflict. Unfortunately, existing indicators typically measure one aspect this general concept, have limited coverage, and/or are not derived independently participation in conflicts. We develop a strategy for constructing measures underlying with data on their background experiences, political orientations, psychological traits Bayesian latent variable framework. Our approach...

Analysis of geometrically complicated waveguide-based slotted arrays and filters is performed using a simple equivalent-circuit model. First, the circuit parameters (inductance capacitance) waveguide slot-coupler problem are obtained through moment-method (MoM) analysis. The values lumped LC elements virtually constant over frequency range interest (the X-band) for specific slot dimensions. Based on model single two coupled waveguides, more structures then analyzed, such as coupler...

AbstractThe effective operation of the American judicial system requires public's confidence and support. High-profile events, most notably Rodney King incident O.J. Simpson trials, have called into question that black white Americans in courts. Contemporary cases (e.g., Kobe Bryant Michael Jackson) may continue trend. While there is abundant anecdotal evidence, rigorous empirical analysis has been limited to studies U.S. Supreme Court. In this article, we explore black-white differences...
