Anthocyanins are secondary metabolites synthesized in grape berry skins via the phenylpropanoid pathway, with functions ranging from skin coloration to protection against pathogens or UV light. Accumulation of these compounds is highly variable depending on genetics, environmental factors and viticultural practices. Besides their biological functions, anthocyanins improve wine quality, as a hig...

Mountains provide as much as 90-100% of the freshwater to surrounding basins in arid and semiarid regions because of their distinctive and complex topography, and the consequent effects on precipitation (P) and evapotranspiration (ET). One of the primary objectives of this dissertation is to estimate mountain-block recharge (MBR), an important component of the mountain contribution to groundwat...

Humidity-dependent current-voltage (I-V) characteristics of Pd-doped vanadium pentoxide nanowires (Pd-VONs) were investigated. Electrical quadruple hysteresis (QH) was observed and attributed to the large amount of water molecules adsorbed on the nanowires. Using QH in Pd-VONs, the reaction of water with PdO was interpreted as the water molecules are desorbed and then dissociated with increasin...

Trends in climate variables important to winegrape production in the western United States include fewer frost days, longer growing seasons, and higher spring and growing season temperatures. These trends have been related to a steady increase in wine quality and a decrease in year-to-year variability. While the trends in climate have been linked to increasing sea surface temperatures in the ea...

This paper introduces a new feedback topology for the Pulsed Digital Oscillator (PDO) and compares it to the classical topology. The ‘classic’ or single feedback topology, introduced in previous works, shows a strong behavior dependence on the damping losses in the MEMS resonator. A new double feedback topology is introduced here in order to help solving this problem. Comparative discrete-time ...

Introduction Pycnodysostosis (PDO) is a rare autosomal recessive lysosomal storage disease of the bone caused by a mutation in a gene mapped to chromosome 1q21 that codes for the enzyme cathepsin K (CTSK). Pycnodysostosis (Greek: pycnos = dense; dys = defective; osteon = bone) was first coined in 1962 by Maroteaux and Lamy [1], although the first case fitting the description may have been repor...

Abstract The stratospheric, tropospheric and surface impacts from the 11 year ultraviolet solar spectral irradiance (SSI) variability have been extensively studied using climate models observations. Here, we demonstrate idealized model simulations that Pacific Decadal Oscillation (PDO), which has shown to impact stratospheric circulation sub-decadal multi-decadal timescales, strongly modulates ...

A unique nanocrystalline, mesoporous PdO-SnO(2) film exhibiting high sensitivity and selectivity to hydrogen gas at room temperature has been developed.

Consumers are very concerned in "Protected Designation of Origin" (PDO) products, namely meat, since they associate these products to quality and healthy foods. Thus, it is necessary to implement analytical methodologies that could assure consumers about the products they purchase. Since this kind of meat is usually sold with no information concerning cattle sex, age and slaughter season, these...

Our objective is to demonstrate an electrospun fibrinogen-PDO (polydioxanone) composite scaffold will retain the superior cellular interaction of fibrinogen while producing a product with the functional strength needed for direct implantation. Fibrinogen-PDO composite scaffolds were electrospun with PDO ratios of 0% (pure fibrinogen), 10%, 20%, 30%, 40%, 50% and 100% (pure PDO) and disinfected ...
