Abscisic acid (ABA) represses seed germination and postgerminative growth in Arabidopsis thaliana. Auxin jasmonic (JA) stimulate ABA function; however, the possible synergistic effects of auxin JA on signaling underlying molecular mechanisms remain elusive. Here, we show that exogenous works synergistically with to enhance ABA-induced delay germination. biosynthesis, perception, are crucial for JA-promoted responses. The auxin-dependent transcription factors AUXIN RESPONSE FACTOR10 (ARF10)...

Cellular components,...

AbstractThis paper evaluates the applicability of multi-beam RADARSAT-1 satellite imagery for mapping surficial sediments in northwest Alberta, Canada, using simple arithmetic algorithms. The goal is to make acquired by Alberta Geological Survey (AGS) usable common users who have no access complex image classification software and (or) expertise. Unlike Canadian Shield, northern mantled with much thicker glacial deposits that are covered Northern Boreal Forest. This limits use conventional...

AbstractThis study has applied persistent/permanent scatterers interferometric SAR (PSI) technology to map ground deformation in the Frank Slide area, Alberta, Canada, using RADARSAT-1 data and EarthView InSAR (EV-InSAR) coherent target monitoring (CTM) software developed by Atlantis Scientific Inc. is a rock avalanche that occurred on eastern slope of Turtle Mountain 1903 claimed more than 70 lives. At foot Mountain, surface above Mine was found subside at an average rate about 3.1 mm per...

Leptospiral immunoglobulin-like (Lig) proteins are surface expressed in pathogenic strains of Leptospira. LigB, an outer membrane protein containing tandem repeats bacterial Ig-like (Big) domains and a no-repeat tail, has been identified as virulence factor involved adhesion Leptospira interrogans to host cells. A Big domain LigBCen2R, was reported previously bind the GBD fibronectin, suggesting its important role leptospiral infections. In this study, we determined solution structure...

The autoantigen La protein is an important component of telomerase and a predominantly nuclear phosphoprotein. As subunit, associates with the ribonucleoprotein influences telomere length. In reverse transcription, stimulates enzymatic activity increases repeated addition processivity telomerase. phosphoprotein, binds 3′ poly(U)‐rich elements nascent RNA polymerase III transcripts to facilitate its correct folding maturation. this work, we identified homolog (TbLa) from Trypanosoma brucei (...

For the purpose of electronic packaging applications, a homogenous and void free 4032Al (Al-12wt.%Si) matrix composite with 70vol.% SiC particles was fabricated by squeeze casting technology. TEM observations indicated that acted as heterogeneous nucleation sites for Si phases in SiC-Al interfaces were clean from any interfacial reaction products. The possessed lower coefficients thermal expansion (CTEs) excellent conduction properties, CTEs could be further reduced annealing treatment...

It observed there no cracking...

In this article, the high-performance modified AlN powder was prepared, using Y(NO 3 ) ·6H 2 O as modifying agent, and characterizing by pH meter, TG , XRD SEM. The results show that Y coating formed on surface, value of aluminum nitride treatment suspension solution maintains 7.75 in water bath for 100 hours. Therefore conclusion is surface modification with rare earths can effectively inhibit hydrolysis powder.

The Coherent Targets Monitoring technique is providing superior ground deformation mapping compared with standard interferometry based on one pair of Master/Slave scenes. This because using a larger data set it possible to estimate and correct for additional phase error sources. Also the point targets detected as coherent are generally characterized by stronger signal that provides more accurate information than clutter present in rest scene. paper reviews previous work SAR noise estimation...

AlN/Cu composite powder was prepared by ball milling method. Laser particle size analyzer, X-ray diffraction and scanning electron microscopy analysis were performed to study powders. The effects of rotation speed, mixing time, weight ratio (BPR) on the distribution, composition, morphology investigated. Results showed that best parameters speed 200r/min, time 6 hours BPR 10:1. In this condition, powders would be obtained with optimum distribution morphology. Then pressed at 500MPa sintered...

Ti-Al-Nb ternary phase diagrams were calculated by Thermo-Calc software.
