ELECTROCHEMICAL METHODS DETERMINATION OF HEAVY METALS IN WINE BEVERAGE ACHIEVING ECOSANOGENE
2014
In this work, we estimated reproducibility and procedures to improve the selectivity of the method and to determine the influence of different analytical parameters (pH, electrolyte composition, deposition time and potential, presence of ligands). Detection limit of copper in samples of white wine and red Blaj (Romania) is 2.4 ppm, with a deviation of 1.5-2,0%. The results were compared with the results by atomic adsorption classical method. The sensitivity of the method is two times smaller, Daton this Pb2- ions.
CONSIDERATIONS OVER A BIOGAS PLANT COMPONENTS
2014
This paper starts from the conviction that one of the main environmental problems of today’s society is the continuously increasing production of organic wastes. In many countries, sustainable waste management have become major political priorities in order to reduce pollution and greenhouse gas emissions and to avoid, as much as possible, global climate changes. This problem becomes more and more present in our country too. Production of biogas through anaerobic digestion of animal manure and slurries as well as of a wide range of digestible organic wastes, converts these substrates into renewable energy and offers a natural fertiliser for agriculture. That is why we consider that biogas p…
Fourfold Increase in Pumpkin Yield in Response to Low-Dosage Root Zone Application of Urine-Enhanced Biochar to a Fertile Tropical Soil
2015
A widely abundant and invasive forest shrub, Eupatorium adenophorum, was pyrolyzed in a cost-efficient flame curtain kiln to produce biochar. The resulting biochar fulfilled all the requirements for premium quality, according to the European Biochar Certificate. The biochar was either applied alone or mixed with fresh cow urine (1:1 volume) to test its capacity to serve as slow release fertilizer in a pumpkin field trial in Nepal. Treatments included cow-manure compost combined with (i) urine-only; (ii) biochar-only or (iii) urine-loaded biochar. All materials were applied directly to the root zone at a biochar dry matter content of 750 kg·ha−1 before seeding. The urine-biochar treatment le…
Caracterización Eco-geográfica de melloco (Ullucus tuberosus C.) En la Región Alto Andina del Ecuador

Ecogeographic characterization of Melloco (Ullucus tuberosus C.) in the high Andean region of Ecuador
 Resumen
 El estudio se llevó a cabo en la región alto Andina del Ecuador, utilizando la colección nacional de Melloco (Ullucus tuberosus C.), perteneciente al Banco Nacional de Germoplasma del INIAP. El objetivo fue evaluar las características de los sitios de colecta, identificar rangos climáticos y ecosistemas favorables o marginales para el cultivo. Para la caracterización se utilizó información geo-referencial de puntos de colecta y 13 variables climáticas, geofísicas y edáficas. Se generó un Mapa de Caracterización Eco-geográfica del Terreno Específico (mapa ELC) aplicando l…
Sport sponsorship in Finland: the case study of FC JJK Jyväskylä
2013
This paper seeks to analyse sport sponsorship in Finland via using the case study of Football Club JJK Jyväskylä from the Finnish Premier League. The results of a master’s thesis conducted on FC JJK fans’ sponsor awareness and sponsor orientation is presented. This research has provided implications to the management of the club, such as how to increase sponsorship efficiency, how to benefit from applying sponsorship alignment as well as relationship marketing. In order to successfully implement the study, an online survey, interviews, and participant observation was utilised. In addition, statistical data were obtained from the club. It has been concluded that JJK fans’ sponsor awareness …
A pedotransfer function for estimating the soil erodibility factor in Sicily
2009
The soil erodibility factor, K, of the Universal Soil Loss Equation (USLE) is a simple descriptor of the soil susceptibility to rill and interrill erosion. The original procedure for determining K needs a knowledge of soil particle size distribution (PSD), soil organic matter, OM, content, and soil structure and permeability characteristics. However, OM data are often missing and soil structure and permeability are not easily evaluated in regional analyses. The objective of this investigation was to develop a pedotransfer function (PTF) for estimating the K factor of the USLE in Sicily (south Italy) using only soil textural data. The nomograph soil erodibility factor and its associated firs…
The internationalisation of the Spanish food industry: the home market effect and European market integration
2015
<p>The objective of this study was to analyse, from a long-term perspective, the factors determining the process of the internationalisation of the Spanish agrifood industry. The paper concentrates on the empirical verification of the existence of a home market effect in the food and drink industries in Spain and on the effects on trade flows of integration into the European Union. With this aim in mind, we took into account the latest contributions to the estimation of the gravity equation for a sample of export flows from 13 agrifood subsectors between 1970 and 2012, with a destination of 175 markets. From the results of the study the existence of the “home market effect” stands out…
GREEN ECONOMY - THE ECONOMY OF THE FUTURE
2013
This paper defines the concept of "green economy", presents the main international organizations that deal the green economy. Are provided details of the most significant principles, objectives and actions of the concept of green economy. At the European level there is "The 2020 strategy ", which shows that Europe's economy should be an economy that knows how to manage resources efficiently and reduce carbon emissions. There are currently a number of basic laws for the green economy. Forest ecosystems are part of the green economy and the forest products industry are very important because they are renewable, recyclable and biodegradable. Thus forests are a fundament of the green economy, t…
Improving soil and water conservation and ecosystem services by sustainable soil management practices: From a global to an Italian soil partnership
2020
The UN Sustainable Development Goals (SDGs) identify the need to restore degraded soils in order to improve productivity and the provision of ecosystem services. The aim is to support food production, store and supply clean water, conserve biodiversity, sequester carbon, and improve soil resilience in a context of climate change. Within this framework, in order to achieve the SDGs and to correct land management in the long-term, soil management is considered mandatory. The reduction of land degradation should be based on various sustainable soil management practices that improve and maintain soil organic matter levels, increase water infiltration, and improve soil water management. This tec…
DEVELOPMENT TRENDS OF BIOGAS
2015
All over the world, researches are made in order to improve the technologies, the operational and process stability and performance of biogas plants, because the world markets for biogas increased considerably in Europe and all over the world. In this paper we studied the most important parameters related to a biogas plant, starting from the ecologic landfill of Cristian, Sibiu, a landfill which storages industrial and household waste. In this respect, we studied operational parameters, such as organic load and hydraulic retention time, and parameters for evaluation of a biogas plant. Also, we made a case study concerning the evaluation of used waters in the landfill described above under t…
