Ascorbate oxidase (AO, EC 1.10.3.3) catalyzes the oxidation of ascorbate (AsA) to yield water. AO over-expressing plants are prone to ozone and salt stresses, whereas lower expression apparently confers resistance to unfavorable environmental conditions. Previous studies have suggested a role for AO as a regulator of oxygen content in photosynthetic tissues. For the first time we show here that...

in this article the relationship between the amount of seasonal rainfall (autumn, winter and spring) and climate indices in iran have been studied. the climate indices (the southern oscillation(soi),the north atlantic oscillation(nao), arctic oscillation(ao),nino 3/4,the multivariate enso index(mei),trans_ nino index(tni) and the pacific decadal oscillation(pdo) are used as independent variable...

Adaptive Optics (AO) systems are widely used in many scientific and medical applications, such as astronomy, laser systems and microscopes, in order to improve the resolution of the image by actively sensing and compensating the optical aberration in the system. This paper aims at improving the performance of a closed-loop AO system with Piezo-driven Deformable Mirror (PDM) and high-sampling-ra...

The Giant Magellan Telescope (GMT) includes adaptive optics (AO) as an integral component of its design. Planned scientific applications of AO span an enormous parameter space: wavelengths from 1 to 25 μm, fields of view from 1 arcsec to 8 arcmin, and contrast ratio as high as 10. The integrated systems are designed about common core elements. The telescope’s Gregorian adaptive secondary mirror...

Every connected simple graph G has an acyclic orientation. Deene a graph AO(G) whose vertices are the acyclic orientations of G and whose edges join orientations that diier by reversing the direction of a single edge. It was known previously that AO(G) is connected but not necessarily Hamiltonian. However, Squire 3] proved that the square AO(G) 2 is Hamiltonian. We prove the slightly stronger r...

Alcohol oxidase (AO) is a peroxisomal enzyme that catalyses the first step in methanol metabolism in yeast. Monomeric, inactive AO protein is synthesised in the cytosol and subsequently imported into peroxisomes, where the enzymatically active, homo-octameric form is found. The mechanisms involved in AO octamer assembly are largely unclear. Here we describe the isolation of Hansenula polymorpha...

Every connected simple graph G has an acyclic orientation. Define a graph AO(G) whose vertices are the acyclic orientations of G and whose edges join orientations that differ by reversing the direction of a single edge. It was known previously that AO(G) is connected but not necessarily Hamiltonian. However, Squire [3] proved that the square AO(G) is Hamiltonian. We prove the slightly stronger ...

Objective- The aim of this study was to assess ultrasonography-derived caudal vena cava to aorta ratio (CVC/Ao) as a novel endpoint in the resuscitation of experimental hemorrhagic shock in dogs. Design- Experimental study. Animals- Ten adult mongrel healthy dogs. Procedures- After induction of anesthesia (con...

In this paper we present a comparative analysis of several currently available Java based dynamic AO systems. The comparison is built on how these systems deal with general dynamic reconfiguration problems. Through this exercise we hope to better understand weather and how do the specific AO change support mechanisms (e.g. total, actual, or collected weaving) affect dynamic system reconfigurabi...
