New Biosensor for Phenols Compounds Based on Gold Nanoparticle-Modified PVC/TTF-TCNQ Composite Electrode
(Electrochemical Science Group (ESG), 2012)A gold nanoparticle-modified PVC/TTF-TCNQ composite electrode with tyrosinase enzyme is proposed as electrochemical biosensor for detecting phenolic compounds in musts and wines samples using phenol and catechol as standards. ... -
Electrochemical Determination of Glyphosate in Waters Using Electrogenerated Copper Ions
(Electrochemical Science Group (ESG), 2012)Carbon electrodes with in situ electrodeposited copper are used to the determination of Glyphosate (N-(phosphonomethyl) glycine) in drinking waters. The oxidation signal to form Cu(II) ions is enhanced after the addition ... -
Electrochemical Determination of the Glyphosate Metabolite Aminomethylphosphonic Acid (AMPA) in Drinking Waters with an Electrodeposited Copper Electrode
(Electrochemical Science Group (ESG), 2012)Carbon electrodes with in situ electrodeposited copper are used to the determination of aminomethylphosphonic acid (AMPA), the major metabolite of the herbicide Glyphosate (N-(phosphonomethyl) glycine) in drinking waters. ... -
Desarrollo de un sistema interactivo de enseñanza virtual para el reconocimiento de minerales habituales
(Universidad de Vigo, 2012)El estudio de los minerales ocupa una parte importante del módulo básico materia Geología, prestándose dichos contenidos muy bien a un estudio descriptivo. Como actividad individual no presencial del alumno se propone en ... -
Utilización de BIOCÁPSULAS DE LEVADURA como agentes fermentativos en la segunda fermentación alcohólica en botella y su aplicación para la elaboración de vino espumoso y bebidas alcohólicas espumosas
(Oficina de Transferencia de Resultados de la Investigación, 2012)Se trata de un nuevo formato de inmovilización de levaduras en biocápsulas, de fácil manipulación, para aplicarse en bebidas alcohólicas espumosas. -
The effects of the tillage system on chickpea root growth
(Science Direct, 2012)A well-developed root system is crucial for plant growth, especially under dryland farming conditions. A two-year field study (2003–2004 and 2005–2006) was conducted to determine the effects of the tillage system on root ... -
Stratification ratios in a rainfed Mediterranean Vertisol in wheat under different tillage, rotation and N fertilisation rates
(Science Direct, 2012)Semiarid Mediterranean climatic conditions and intensive tillage systems accelerate soil organic matter losses. Therefore, assessing agricultural practices that enhance storage of soil organic matter is needed. Stratification ... -
Wheat response to nitrogen splitting applied to a Vertisols in different tillage systems and cropping rotations under typical Mediterranean climatic conditions
(Science Direct, 2012)The application of an adequate rate and splitting of nitrogen (N) is essential for the efficient use of N fertiliser and to maintain the economic sustainability of cropping systems. A 3-year field experiment was conducted ... -
Nitrogen remote diagnosis in a creeping bentgrass golf green
(Science Direct, 2012)Nitrogen fertilization is a key factor of the aesthetics and playability for golf greens. Nitrogen fertilization management is based on predetermined scheduled applications, set rates, or expected improvement in visual ... -
Nitrate accumulation in the soil profile: long-term effects of tillage, rotation and N rate in a Mediterranean Vertisol
(Science Direct, 2013)Excessive application of fertiliser in agriculture can have detrimental effects, one of which is diffuse contamination with nitrates. An 18-year field study was conducted on a typical rainfed Mediterranean Vertisol to ... -
Nitrogen rhizodeposition by wheat under different tillage systems in a rainfed Vertisol
(Science Direct, 2013)Roots and the nutrients that they deposit into the soil are a natural source of N for a current crop, or a subsequent crop in the case of rotations. Despite the importance of this process, there are few field studies of ... -
Chickpea water use efficiency as affected by tillage in rainfed Mediterranean conditions
(Science Direct, 2013)Under rainfed Mediterranean conditions, chickpea production can be increased by improving the soil water content (SWC). This study was conducted on a Vertisol in southern Spain over a period of ten years (2000-2009) to ... -
